yes it's direct replacement for your stock rear.With 3.55's and 26" tall tires my mav turned 3000 at 60 w/3500 stall,2800 w/stock converter,2800 w/3spd manual.
Currie, Randy's Ring & Pinion are a couple. I'm sure there are more. I would stay away from Perogie. 2 of my friends have bought stuff from him that just wasent right.
Just like the Maverick, Pintos and Bobcats could have either the 7.5 or 8 inch rear. Engine size or number of cylinders does not matter. If the car has an 8" rear, it breaks down something like this: 4 cyl auto tranny: 3.40 with optional 3.55 4 cyl manual tranny: 3.40 A/C cars are 3.55 standard if memory serves. V6 cars are 3.40 and the trac-lok was optional. The rears are small bearing 4 lugs, so the only part that is interchangeable with our 8" rears is the chunk. Identical. You wouldn't want to use anything else anyway. I am surprised this stuff isn't common knowledge here. Now that the cat is out of the bag, I'll never get a cheap Pinto chunk again... Dave Edit: Late 60s-early 70s: Fairlane, Torino, Ranchero, and maybe others... The 3.28 gear is common in 8" rears for these cars. I have no idea about the availability of trac-lok. Just in case someone wanted a very mild increase over the 2.79-3.00 gear set.
Yeah, I knew about Mustang-IIs, but I never knew about Bobcats. I wonder if any of them actually had Trac-Lock. Will have to keep my eyes open for them as well now. Buddy of mine wants some better gears than the 2.79s he's currently running...
