will a 5 inch offset fit a speedway brake conversion on the 57 swb?

[la hi]

I converted the front brakes on the 57 swb to disc with the speedway conversion kit. The brake conversion works great!! Then I put s-10 alum wheels on and they do not fit perfect. I am afraid they may come off some day.

I have decided to go with plain ol ralley wheels on the front. The pair I have found have a 5 inch offset.
Will the 5 inch offset work? Speedway tec dept said they do not know.
