The FINAL Wheel Backspace Thread for 1967-1969 Darts

Ok, probably not....but,

I guess I just need to know what BS is going to work with my Factory A-body 8 3/4, mini tub and spring under frame relocation...
Will a 15x10" wheel with 7.5" BS work with a 12.5" cross section tire?
Planning on moving the axle back about .75" as well so I can use a 29" diameter tire if I need to.
