Can anyone tell me what the bolt pattern is for a stock '72 240? 4x100 or 4x114 or what?? Thanks!!

114.3

Thanks cbudvet. I appreciate that.

114.3

= 4.5 inches which was a common bolt pattern at the time.

I had no idea that 114.3 = 4.5 inches. Do they use millimeters because they are from Japan or is there another reason?

Back in the day, we used the standard system here exclusively so bolt patterns were in inches. I think various parts on early Z cars are standard and others are metric (could be wrong). But the standard 4 - 4.5 bolt pattern (4 Bolts spaced 4.5" apart) works out to 4 - 114.3mm, given that there are exactly 25.4mm in an inch.
