Recently did an 8.8 swap, meaning I need to change out my rear wheels to15" BBP. I'm looking at local set of 15" BBP rallyes that are either 6 or 6.5 (he's not sure) and my concern is the center hole size. I see that most aftermarket are 2.75 but I suppose that's not exact. The index on my axles...

Anyone found front drums and hubs for a V8 Dart (273) that have the larger lug pattern? I went with the 5x4.5" for the Dana 60 in the back, just want to match it up front, and the Google machine is laying goose eggs for me at the moment (or it might just be me) :).

I have for sale a complete Kelsey Hayes BBP 5 on 4.5 disc brake setup. This was pulled from a 72 challenger. Has very nice used rotors, pads, and calipers. Includes spindles and lines too. This uses the 1973-1976 and later A body K772 large upper ball joint. This will bolt up and swap out your...

Ok, no matter how many times I bleed the brakes I am getting air in all 4 corners. Car is a 1968 Dart, factory KH disk car. I did the 8.8 swap for rear disks and 73+ swap for BBP. All new soft lines and calipers on all 4 corners. New 15/16ths master that was bench bled. No visible leaks, no...

Hello, I’ve got a 1971 Plymouth Scamp that currently has small bolt pattern and all drum brakes. I’m looking to swap the front brakes over to BBP disc brakes from a 1973 and up car. I am looking for everything I need to do this, a complete setup is what I’m after. I am located in North...

On my 71 duster I currently have a 7 and 1/4 rear I purchased an a body 8 and 3/4 with backing plates for and 8 3/4... ( With new shock plates)It's currently a slant six car with a 904... One day I would like to put a 340 in it but that's not for another year or two out and wanted to do a few...

I need to swap out my rear axles from the 5x4 to the 5x4.5 on my 8-3/4. I thought it would be easy but I get more confused every time I reach out to a manufacturer. I understand that the offsets are different and was told I need to change the backing plates as well. I asked Dr. Diff but he did...

have a 7&1/4 in a 73 dart & the mag wheels/tires are very close to the outer fender. I would like to swap to an 8&3/4. Are these pretty much the same total width? thank you for your time. RR

i have a 8 3\4 rear and changing to big bolt pattern and looking for brake parts for the swap. Are all bbp backing the same other than brake diameter? Is there different backing plates for the different widths? Will 1\2 ton parts work or do they need to be for a car? Any specific model? Any to...

I've done many searches on this and I'm still not 100% sure. I have a 3.55 geared 8 1/4 rear out of, I believe, a 97 Jeep Cherokee. I'm intending to install it in my 73 Duster this winter. I am fairly certain that the 10" drums from my current BBP 7 1/4" axle should be a direct swap to the...

Hello everybody it’s been some time since I posted a question on here but I’m on need of some guidance. I recently got my second MOPAR, it’s a 74 Dodge Dart Swinger with a 318. My rear end recently locked up so instead of rebuilding it I decided to try and save a couple bucks and get a...

I’ve got a 1974 Valiant with front discs so I’ve got bbp. I have an e body housing im having shortened and I have a body axles that have been drilled for bbp. I’m assuming I have 10” in drums in the rear which I’m hoping to use. Can I use the backing plates from my 7.25? And is there anything...

Hey guys, I'm looking at options for my duster when I do a front disc brake conversion to get the BBP in the rear. I'm reading through the ford 8.8 thread, but I also had an epiphany late last night. I looked it up, and an XJ cherokee has the 5x4.5 bolt pattern, a centered pumpkin, and a...

looking for a rear end for my 72 duster currently have a 7.25" with SBP 9" drums but want to upgrade. Will consider pretty much anything with BBP Thanks in advance!

On my 70 Duster I currently have a stock 8 3/4 with sbp (5 on 4) axles. I recently picked up a set of bbp (5 on 4.5) axles to swap out. Will I need to swap out the entire drum brake assembly, backing plates and everything else?

I posted this in another thread but thought it might be easier for someone searching in the future to find in a thread specifically about this. I recently swapped axles in a 7.25 rear from being 4” bolt pattern to 4.5” using axles and drums that I bought from Doctor Diff. The axles have the 4...

Selling the disc brakes off of my 73 Plymouth duster. This will fit all A body mopars and will include everything needed to swap over to large ball joint 5x4.5 disc brakes ( minus the spindles). Included - Rotors Calipers Caliper brackets Brake pads Upper control arms and ball joint Dust...

I own a 66' Barracuda and I want to switch those old drums into all around disc brakes. I was looking into buying a set kit, so that I can put it in myself. Most likely power instead of manual with the booster. I found this kit, that seems to be the best option at this point. Do you guys...

Hello all, I am working on my 74 dodge dart and unfortunately my front hubs and drum covers did not survive due to rust. I having a hard time finding what would be good to replace these. The wheels are 14 inch and it is a 5 stud pattern. Does anyone have any suggestions?

Recently converted my '70 valiant to big bolt pattern. The original SPB spare doesn't fit anymore for obvious reasons. Looking to see if I can locate a BBP steel spare wheel to replace it and keep the car fairly complete. I don't necessarily need the tire, I can swap over the original as it is...

So I am helping a little cousin to getting into mopars. (He's 20 and might join here) I located a duster for sale from a semi local guy I've known for years. There are 2 dusters for sale. 1975 duster with a transplanted 360 and auto on the column. It was a slant car but has an unknown...

A local fella parted out a 73 duster, and viola, I am doing the swap in two weeks. I got upper control arms to ball joint. I ordered the correct ball joint for the swap- shoots, I should say, it's a 4 door 68 dart, will post a pic of it. I am going to BBP for wheel selection, and of course...

I have laid off the ol' wifey dart, had lots going on, but collected a part or two here or there- the Dr Diff was the biggest piece. So what am I doing? Basically, I am doing a BBP brake and suspension swap on it, and putting 15" rims and replacing the 13s. It sits so low that I can't even...

Some of you have seen my post about my 14 yr old son getting his wrench on and bringing home a $400 73 Sport. That thread is here: My next young gun is starting to get his wrench on..... The search begins... I figure I might as well start a restoration thread of sorts, to introduce y'all to...

I have a 77 Volare complete front discs set up that I want to swap to my 70 Dart with Kelsey Hayes disc. Ive read up on it here. What additional parts will I need to make the conversion? Are parts for the Volare discs readily available ? Will mods need to be made ?

Hey everyone, I was originally planning on putting an 8 3/4 with my slant but they are just far too expensive and I noticed there are a lot of Dana 60 rear ends out there for cheap. Does anyone know if the Dana would be too much for the slant or if it's something I could deal with for a...

Welcome to my build thread. I snagged this 72 Duster at mid-October of 2022 for 7k. It came with a slant 6, 904 combo with a 7.25" rear, manual drum brakes all around, manual steering, and A/C! Interior was insanely clean for it's age, seats had been reupholstered. Suspension sagged, 14"...

So I am in the process of swapping out the center section on my 8.75 rear axle from a 741 case 3.23 open to a 489 case 3.73 sure grip unit. I also acquired a set of a-body BBP axles that I would like to put in so I can get rid of the SBP to BBP spacers/adapters that are currently on my street...

Hello There FABO I am going to be converting an E Body 8 3/4 to fit my 1972 duster. I have already done some research and looked through the sticky thread "An accurate 8 3/4" rear axle width list". I wanted to reach out to any members here on the forum who have converted an E body 8 3/4 to an A...
