Big bolt vs Small bolt

This is how I've always been told to measure BP:



Not to be a jerk, but it's not as simple as "across two studs". With a 5 lug pattern, the measurement needs to be taken from the back of one stud to the center of the stud directly across from (not next to) it. Someone who is unfamiliar with this could measure across the wrong two studs and come up with an incorrect dimension.

That's what I was getting at. OP is obviously just starting out on the Mopar journey, so it's always a good idea to clarify stuff.
