Getting ready to put the lower A arms on my 67 and noticed that I have 2 different size ubolts? Where can you get the right size ubolts? thanks Rick

Re: 2 sizes of lower A arm ubolts?
I recommend upgrading to the larger '73 and later versions. They are beefy 9/16" u bolts that eliminate the breaking issue GM had with the smaller ones. You just need to drill out your bolt holes in the crossmember.
Search for Dorman 13503 for the larger ones. Amazon has them as most parts stores.
