6 months ago I bought new 16 inch tires for my 40 1/2 ton. Now I am going to change out the rear end for a 52 powerglide to get a better gear ratio. The 52 has 5 hole 15" wheels and I want to keep my new 16" tires and wheels. There is not enough material on the axle flange to redrill the larger 6 hole pattern. Does anyone have a better idea? I know I could buy yet another rear end from a 48 or older car but I am trying to avoid the expense and the work of doing that. Thanks for any help. Dale
