15 x 10 wheels on a 71 roadrunner, bs needed

[340runner]

Has anyone ran 15 x 10s on their 71 roadrunner and can it be done, if so what backspacing is needed?
Stock length 8 3/4

Also, what backspacing should I run for frontrunner wheels? Thinking 15 x 4.5 but unsure of bs needed.

Thanks,
Paul

Thanks, any knowledge on the fronts?

I wouldn't be surprised if the fronts being 4.5" wide are spaced in the middle.
I have 15 x 3" Welds on the front of my Runner with a 27" tall radial Mickey Thompson Radial tire.

Most 15"×4" front runners are a 1-7/8" b.s.

Mostly, Some are 2 1/8 or 2 1/4

On our 73 Roadrunner stock eliminator car we
run 4 1/2 BS on 10 with our 71 Dana 60.

I run 2 different front runners on my cars. Both are 1-7/8" b.s. Currently, they

happen to be on my Challenger.
