1966 Disc Brake Conversion Questions

It's not hard to source the parts for the later Mopar swap. An hour or less in the yard gets you everything you need off an F/J/M body except for the UCA's and lower ball joints. If you buy new rotors, calipers, and hoses even faster, since you don't need to pull those parts.

Heck, you can go on RockAuto and source the master cylinder, rotors, calipers, and hoses. Using their current prices for '73-'76 A body disk brake parts...

M/C- $11.23
Rotors- $36.79 each
Calipers- $39.28 (includes a $20 core) each
hoses- $5.88 each
pads (semi-metallic)- 7.12
lower ball joint- 17.20 (each)

So that's $223.77+ shipping. Last set of spindles and caliper brackets I got from the yard were $60. Throw in the brake block, we'll even call that $20. So now you're at $303.77. Buy a set of ball joint sleeves from Dr. Diff and re-use your UCA's, $50.

So, $353.77 + shipping from RockAuto. Everything but the spindles and the brake block were ordered new, and you've got Mopar LBP brakes, just like the factory. No chevy parts, no extra machining, everything can be had from the local Napa in a pinch. I don't understand why you'd want to buy a kit to put chevy parts on your Mopar when you can get the Mopar parts for the same price, and that's using all NEW parts except for the spindles and brake block. Find decent parts in the yard and you can start subtracting costs.

AND, if you get really lucky and find a B/R/M body out there, you can have 11.75" rotors, same price for everything. Or, spend an extra $100 and order the 11 3/4 caliper brackets from Dr. Diff new.

I searched for a set pf Upper control arms and spindles at darn near every yard in my area. seem like they scrapped all the older models and only had FWD card or later models and if they had them they were 120.00+ . I even went on here and looked. 150-250 USED for a setup that I'd have to add new upper ball joints new calipers and rotors hoses and brakes hoses and lines just didn't seem cost effective to me. also if I go with the later spindles it widens up my wheel track width. bout a 1/2 inch or so. I'm stuffing int he biggest tires front and rear so that limited that idea due to me knowing that I'm not going to bend in the front fender to get tires to fit. total cost would have been Wayyyyy more than the 380 or so I have in an all new from the spindles out. At least by the cost of the used parts I'd be putting on,spindles,caliper brabket and BBJ uca. just to use stock parts that are getting harder to find new or used.

yes I did replace all my bushings(offset all the way around on the UCA) and ball joints and tie rod ends but that was something I'd do any way on an older car I planned on driving the heck out of.

it all Boils down to money for me. if I can get the bolt pattern I want (5 on 4.5) and keep the front track I want. using any kind of part that is new and safe and fit correctly I'll do it. I really won't put a chevy engine/trans in a mopar , of course I'd stuff a hemi(if I had one) in anything. but as for steering components,suspension and braking components they made by "moog,TRW Monroe. ect.."(or other parts companies) and "moog" doesn't give a crap what car they go on to to make stop-turn or soften potholes they make a part that does a certain thing the ordering company wants. that's just like saying the chrome plating company put "chevy chrome on my mopar". or that holley is a "ford" holley why did you put it on your mopar? or your turn signal flasher fits a toyota too! "quick yank it out or it'll contaminate my car" or :the list goes on and on.

I'm good with you wanting to put only mopar parts on you mopar.

But in my area and on the web those parts are priced as gold.(again the money thing) but you now have options and yes one of them is a P-S-T kit or just suspensions and many others.
Another way is how I went (scarebird). it fit's and works and I only had to do 1 machining process that I was going to do anyway(5 on 4.5 bolt pattern on the hub $40.00) and it's basically about what you(or me or the other guy) wants to pay and put on their car.
