Bought It 72 Demon
Here's an important note before I give you my tire/wheel combo: I have a '65-'67 B-body 8 3/4 rear (54 1/4" flange to flange) with offset spring hangers (3/4"). Wheels are 15x8 with 5.25" backspace. Tires are Nitto Drag Radials 275/50-15. I'm fairly confident I can fit 295/50-15 tire with no problem.
This could be useful when you get to picking tires/wheels so I'll post it here.
My measurements:
Frame to inner side of spring (ISS) 3 3/4"
ISS to brake drum 6" (limits wheel backspace to 5" or so depending on tire)
ISS to inner fender lip (IFL) 11 1/4" (limits tire width to about 10.5" assuming perfect backspace - 1/2" can be gained with fender lip trim)
Frame to IFL 15" (max tire width with springs relocated is about 14")
IFL to brake drum 5 1/4"

A body is 57 1/8" drum to drum.
Your B body should be 59 1/2". With your extra 3/4" you have 12" total space and about 7 15/16" spring to drum. With your 5 1/4" backspace there's lots of room inside.
Section width of your tires is 11.3". A 295/50/15 is 12.2" so unless my measurements are off these would need a spring relocate or lip trimming and perfect backspace to get inside the fender.
Here's a bullitt wheel that I think would look awesome and fit inside the fenders. Hard to beat the price.

This tire, by my calculation, with section width of 11.57" would impact the fender lip by about 1/4" so a trim job might get it in there. You'd have about 3/4" on the inside.

(Note that the 295/45/17 has lower SW than the 295/50/15.)
Of course my calculation could be entirely bogus :iconbigg:
(I think I've got a case of tire & wheelitis.)
