Did a search on the board but couldn't find a topic talkin about it so here's my question :
How can I know if my car has the SBP / LBP? I heard some disc brakes darts had it, is that true?
My car is a '67 Dart with power disc brakes (and power steering).
Thanks for your help

Measure the distance between 2 lug nuts across from each other (not exactly across as there's 5 nuts).

When you measure from the center of 1 stud to the outside edge of other stud, you'll either get close to 4" (SBP) or 4.5" (LBP)

SBP has 7/16 bolts and LBP has 1/2 bolts.

I used a new 20 dollar bill as a tool when I was shopping for SBP wheels.
On a LBP wheel, the corners touch the hole (or stud) centers.
On a SBP, one corner is in center and the other corner touches the far edge of the next hole.
