79 wheel backspacing ???

Have a friend that just aquired a 79 C-10 and is looking to run 15x8's up front and 15x10's out back. Anyone know the correct backspacing for this setup?

Thanks in Advance.

Factory 15x8 has a 4.25 bs.
15x10 with a 5in bs is perfect.

I have the the 15x10s/5in bs on my 82 with a 10bt rear w/295/50/15s with a 4.5/5 drop.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
