1972 Imperial - Bolt Pattern Question

Is the bolt pattern on a 72 Imperial larger than b-bodies? What is standard on b-bodies, 4 1/2"? I thought years ago someone told me that Imperials have like 4 3/4 - or that Chevy rims would work?? I'm wanting to start searching for some torque thrusts and figured if they're the same as a Chevy, I could increase my chances of finding used ones on some of the chevy sites.

Thanks in advance for the education!

Seems like they are 5 on 5 bolt pattern, I am not sure GM stuff will clear the calipers or have the correct backspace
Did you try posting a wanted ad in the Full Size section?

Are C-bodies 5-inch?

all C-bodies are 4.5, Imperials(technically are not C-bodies) have 5" pattern up to '73 or so then use 4.5" in '74-later IIRC. There are a lot of '70's-later Chevy trucks with the 5 on 5 bolt pattern.

Police Impala and many Station Wagon models with HD brakes had the 5x5 pattern. ALL 5 lug full size trucks were 5x5 as well.

Not all 5 lug full size were 5 on 5. This change was done sometime in the 80's I think. I do know that up through '78 the D100 & D150's were still 5 on 4 1/2. That is the latest year 1/2 ton I had.
