changing axles on a 1991 2wd toyota pickup
I am looking to purchase a rear end out of a 1991 Toyota pickup to install in a 1933 Chevrolet. It is the closest to the original 57.5" original one that is init now. I found one out of a two wheel drive that has the correct gear ratio, 3:42's, but is a five lug and I need 6 Lug. Are the axle housing on the two wheel and four wheel drives the same lengths? Also, are the axles interchangeable(5 to 6 lug)?
