Backspacing

What would be the back spacing on a 1964 goat with front disk, I measured 4 3/4 with cragar mags

I have gotten to as much as 5 1/8" backspacing with some disc brakes. All depends.

The BS required will vary by the width of the rim and the size of the tire.

I ran 15x7" with 4.25" BS while running 235/60/15's (26.1" tall) and that was tight with my front disc brakes.

I now run 17x7 with 4.625" BS while running 215/55/17's (26.3" tall) and have plenty of clearance.

Not much information here to make an assessment of your situation.
