wheel offset

Yea its something like that.So if you are running amigo fenders you measure the difference of the fenders and that away some of the back space we said. What are you going to do on the back for clearence there?Shorten the axel or widen the bed?

Ha well thanks guys. I suck at math. Looks like 6 7/8" backspace it is

I've owned 2 Isuzu's plus helped build another so I got good at backspace. Watch out on the back like Paul said cause I think 6 7/8 is the most you can get on a rim. If so its flaring time for the bed or axle shorten time.

They had to flare the bed on bone collector to fit the wheels on the back.

Yeah I remember that Paul. I guess that was easier then molding on a set of Amigo fenders to the bed. I've seen that done to.
