'72 rims

[scott72]

Guys,

I was checking out these rims on Jegs:

But, I wasn't sure if the backspacing (3 3/4") was fairly standard or not.

I might end up dropping the car at some point in time, but probably not any time soon. I was suggested to get the 15x8 rims.

Also, someone said that I should have a 5X5 bolt pattern, but I measured it on the rear end, and I swear I got 5X5 1/2.

If anyone has any suggestions, let me know. Thanks.
