maybe an earlier 3/4 would have a setup you could use or maybe a big block one. thats a good idea to get the carrier bearing setup from something that had it probably be alot less, my old man had a 350 3/4 from that time and it had a 700r4. i had to have my 400 rebuilt anyway into a racing one so it wasnt any more hardly to have it done then.
thats why i dont live in town, if i want to grind at 2am nobody is going to say anything, except my wife, lol
