I can't locate my parts for a picture of the 2 side by side. But they are different. Also through the years GM used at least 2 different size bolts. So check that before you swap the arms. Some spindles use a 7/16" lower bolt and other use 1/2"
If you have to you can drill them out. In my case the A-body used smaller bolts.
