Lower control arm U Bolts - part numbers? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Merry Christmas Gentlemen!

Apologies, I have used the search function but not found what in was looking for.

I want to upgrade my LCA U bolts to the larger 9/16th version (Truck is a 66) but am struggling with the usual suspects web sites when it comes to finding them.

Being based in the UK I can't use NAPA and the like (they don't ship).

Could anyone point me in the right direction?

As an aside, if any of the online restoration suppliers are reading, please sort out the search function in your sites!

Dorman 13503. I don't know what path you order being from over there, but that's a very common number available from most near any parts store, Summit Racing, Amazon.com, pretty much any place.

Here is the perfect thread for you to read. The guy is updating his U bolts just like you're wanting to do.

I believe I have a pair of the thicker u bolts at home. They are greasy and dirty but ill measure them to be sure. If they are what you are looking for you can just have them for whatever shipping is.

Is the od of the bolt 9/16?
