Thanks for the imput Marc. The 57 has an open drive line,i have been considering dumpin the truck 3 speed,for a bel-airs 3 speed,and i have found a vendor sellin 3.8 to 1 ratio ring and pinon sets for the stock rear end..And well,being young and dumb,and still having a young mans back,breakin stuff aint so bad,hell half the fun for me anyway is fixin it..
