Help with backspacing!! 20's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've searched every word combination I can come up with and can't get a good straight answer.

Heres what I've got:
Its a 68 SWB with CPP 2.5" spindles and 2" springs.
In need of a rear at the moment but want to use specs for the narrow rear end.

Closest answer I have is somebody running the wider rear & 315's with 4.75 and some "massaging"

Wheels will be American Racing Salt flats, 20's. Need to order soon..
Wanting 255's front and 315's rear...possible without surgery?
