On the rear, inside rim to rim is 54 1/2. Box is 48 1/2". My tires are 600 x 16 with 4" wide rims. On my stock 41.
On the s10 conversion you can use a 4 wheel drive rear end, it is wider than the 2wd.
I can measure both 2wd and 4wd unless you already know what you have. I have both and easy to measure. Dave
