Rear wheels on '68 Step side??

[FirstGen]

Ok guys, here's the problem. I'm itching to get wheels for my baby, but the body shop is taking longer than expected (it always does huh). They have the bed off the frame and all that so I can't do my own measuring as I would like to.

I want to know if any of you with a 67/68 Stepside can take off a rear wheel and measure two things:

#1) The distance from the mounting pad on the drum, to the to the box of the bed or (max backspace)?
#2 From the mounting pad on the drum to the inside lip of the rear fender?

I would really appreciate it if someone can check this for me! I'm hoping that someone already is working on their truck and can just measure this for me really quick.

Thanks alot,
Taylor
