If you are thinking about going with a new rear axel, drive shaft and five speed tranny, there is a 12 bolt posi with 3.42 gears in the swapmeet, with 6 lug bolt pattern- so you could use your stock rims, and it appears to be the same width as the original axel in my '51.
'51 Chevy 1/2 ton w/'62 261, HEI, offy, fentons, dual carter/webbers, t-5 & 12 bolt posi
