If so used 8 or 9ins are not rare and can be found locally pretty much at any junk yard or part out. Brake upgrades are a must and can be found at any mustang parts site or summit or jegs also a good idea to upgrade to power brakes at this time.
Also you'll need v8 suspension parts or else your front end will sit way low.
I have a straight six in my car and job swapped everything needed for a v8 now.
What I went with was,
8in out of a 67
Wilwood 4 piston calipers
Power booster and dual master cylinder from national pats depo (then swapped to a wilwood master)
And recently had my c4 rebuilt
Upgraded brake lines to braided/ v8 size ss brake lines.
Also not needed but with all the new power of the v8 the stock steering geometry isn't the best and your already going to swap springs might be the time to look into the Shelby drop and maybe new bushings.
All of this isn't needed, besides the rear end but then you won't have matching tires. Just depends on your budget and time. Which is all way I decided to get all the parts needed for the v8 before I got one. But how is the service at your engine place? I'm thinking about getting a 390 from them for a different project.
I am just curious as to why you went with the 8in rear? I am not doubting your decision but was curious as to how strong they are. I had a '76 with the 7.5 but with a 372hp to the ground 302 it lasted longer than any of us ever thought it would with countless 6000 rpm clutch side steps. It would probably still be going right now if I still had the car.
I am going to pick up a '65-'70 fastback hopefully soon so that was why I was wondering on the 8in strength. Thanks and sorry if I derailed the thread.
