Guys,

I need help.
I own a 1971 dart that I am putting disk brake conversion kit on. I am having trouble with the rear end. I guess my car has an 8.25 rear end with small pattern lugs and the brakes wont fit it. I need either an 8.75 or Dana to make it work. According to Summit tech support, they do not make a kit for the 8.25 rear end.

So either I shell out big money for the rear end needed or I have mismatch rims. wtf.


Can someone help me figure out what to do. Those rear ends don't grow on trees these days and i am not rich.

Thanks in advance.
 
I have never seen an 8.25 with SBP axles. I was under the impression the 8.25 started in 1973 and was BBP. BTW, the jeep cherokee disc setup looks a lit like the ford explorer setup. A company called www.bruinbrakecables.com can custom make you brake cables with whatever ends on them that you need. They made me brake cables that were mopar in the front, and ford explorer in the back

Mam, that's cool!
 
Thank you. I think they say these are good till 20,000 psi pulling force on them before failure

I tried to get them to do some early A cables for about a month by phone and email, never could get them to follow thru...
 
This info is a little dated pre 2000
8 ¼
Introduced in 1969. This rear end will be found in all Darts / Valients from 73 - 76 and also can be found in 340 Dusters and other A bodies. There is a sure -grip available beginning in 1973. This axle while not a real high performance piece is certainly good enough for a mild street car. So if you go for a disk brake swap and are pulling out those spindles etc. out of your 73-76 donor car just grab the rear and you will have a nice 4.5" wheel pattern all around and way better brakes to boot. Sure-grip units are commonly found in Diplomat cop cars throughout the 80's but that rear end is a bit harder to install than the 73 -76 due to the strange leaf spring mounting pads. These pads can be cut off the axle and replaced with more conventional ones if you wish. If your short on cash and you can't afford to get a 8 ¾ or find the time to locate the long 8 ¾ axles for re-splining the 8 1/4 is a real nice alternative for a while and CHEAP in the yards ($50.00 non sure-grip and $125.00 sure-grip here in Texas). You may never blow up the 8 1/4 with a mild small block street car.
Castings: 2852905, 3723598, 3723599
Info: 1 5/8 pinion, 57.6" wide, 10 bolt cover, 55.6" width (flange to flange) / 51.4 housing flange to flange / 43.02 spring seat center to center.
 
8.25" is a great rearend. Sounds like you probably have a 7.25"
