GM Abody bolt pattern

Hey,
Is the GM A body 70-72 (Buick GS!!!) bolt patern 4.5 (4 1/2) inch between the holes?????Or is it 4 3/4???

I think the GS has 4 1/2 right and the big cars got 4 3/4!???

I remember trying to fit a Riviera wheel on my GS, it would not fit...

(PS, just to lazy to go and mesure......Im sure you guys know this stuff!!!...Thanks!!)

 

If my memory is right, its 4 3/4 inches for the A-body's and 5 for the full sized cars.

 

Steve is right.

ditto:laugh:

 

What would my 65 special have, I hope its 4 3/4

 

so would i,its all that fitsp

 

Ok, to clarify for future doubts, GM front wheel drive cars are 4 1/4 bolt pattern, rear wheel drive mid-size are 4 3/4 bolt pattern, and full size gm rwd are 5 on 5 inch. Write it down, print it out, tattoo it on your hand. Just remember it.

A 2002 Monte SS is actually a 115mm/4 1/2" bolt pattern, not 4 1/4.

 

And for the measurement on a 5 lug wheel , you measure from outer bolt #1 to center bolt #3

68-69 A-body are 5 x 4 3/4 as well :TU:

 

yes, something i guess my tire shop didnt know when he ordered rims for the a-body at 5 on 4 1/2, which means when we went down and paid and they installed the tires and then figured out they didnt fit (but boy did they try to get them there)

Guess i should have expected it since my custom offset tires came back .5" too narrow, which left my tire rubbing my frame on the drive home and back to get them removed.
