Wow, tons of good advice, thx everyone.
I just found a 1970 F250 with a 390 that runs pretty nice. I'm waiting for the guy to get back to me on the rear axle code. Looks like the f250 could be anywhere from 3.73. to 4.56. Sure hope it's a 3.73. From what you guys say I'd like about a 3.50 - 3.89ish positrac.
Can anyone tell me if a 1970 f-250 2 wheel drive is basically the same 9inch rearend as my 59 t-bird? I would think they have different axles, but could the pumpkin be the same?
thx, dave J
