Car is a 1976 Cordoba, I will be running 275-60x15 tires on 8" steel wheels, I have a choice of 3.75" or 4.75" back-spacing, does anybody have one of these combos that could advise me on what works for them for clearance and appearance issues or better yet have any pictures? Thanks!

3 3/4" = not enuff backset

4 3/4" = too much backset

4 1/2" = just right on backset

remember to include the tire sidewall bulge and leaf spring clearance when measuring backset for rims.

4.50 backset is perfect for most mopars with 7"/8"/10" wide rim.

on my 76 Daytona Charger SE I ran a 10" wide rim with a 4 1/2" backset with 275/60/15 or the N50/15 = 325/50/15
