15 x 7 rims with 3" or 3.25" backspace (BBP)

I doubt a steel 15" wheel exists with that Back Space.....I have a set off a Chrysler 5th Avenue that are 15x7 but the BS is 4".

Good luck keep us posted.

Been digging around, nothing stock was made with this backspace it seems and the only aftermarket steel rims are Bart circle track racing units with 7/16 lug holes.

I may get a set of "police wheels" done by Stockton.
