going to be building up an 8.75 for my 67. i pulled the brakes off the 7.25 from my parts car since they were 10x2" drum setups. they will fit the 8.75. i had a 7.25 from my 67 bcuda /6 and the one from my 74 dart parts car. didnt want to mess with them, they added $$weight$$ to my scrap trailer , along with the slant, and 3 speed manual behind the slant, and slant 9" brakes and slant K frame
the slanty guys will prob flame me for that, but i tried to sell some of this stuff off a couple years ago when i was pulling the cuda apart for its restoration and transformation to a V8 car. nobody wanted any of it. so i got scrap weight out of it, and the leftovers from my dart parts car i couldent sell, or intend to use myself.
from following the thread, its a roll of the dice apparantly with these lil peglegs. ya may get a good one to beat on and it not break, or ya get a hand grenade that goes boom the first time you stomp on it. i gave the 8.8 mustang / explorer rear a thought, theres lots of gear options for these, the BBP setup, rear discs, etc, but decided to stick with the sexy 8.75 with finned drums. i love that welded on rear cover. "smooth"
theres many ways to do this one, best way to do it is within your budget, and time frame you need it. my cuda is a looong term project, i can lurk on evilbay and other placed like craigslist till i come up with the right parts cheap to build it up.
i like to swap n trade to get what i need. so far im into my build up for $625
742 center chunk and housing from C body $100
clutch type sure grip $75
A body axle housing $100 (score they didnt know what they had)
new A body axles BBP w green bearings $300 (ebay)
completely rebuilt rear drum brake setup $ 50.00
i have a friend who does 9" fords for circle track. very close to an 8.75. he offered to set up mine for beer LOL. i got to get the bearings, rear end gears, and clutches for the sure grip. then we hot tank and build the chunk.
good luck whichever way you decide to go on your project.
