lower control arm bracket change?

[chevyguy_72]

Just wondered if any one has ever change the lower control arm brackets?
Looks like they are held in with a rivet... When taking the truck apart the other day i realized the alignment pin was sheared half way off... could be the reason i alway have problems with the header hitting the lower control arm on that side...
I see LMC has them but not sure who else... just looking for anyone else to chime in with where they got part and how the change out was?
Thanks

Haven't done this myself, but on one of the thread I saw where they removed the rivets, replaced the center pin with a regular socket head cap screw (to locate center) and two button head cap screws where the rivets were. They used locking nuts on the top, hope this helps...Jim

You might be referring to my build thread, where I replaced the rivets with socket head screws. I did a caster mod and I wanted full engagement between the locating pin and the lower control arm cross bar. When I pulled my truck apart, the rear rivets were not long enough to even pin into the bar, so I was only pinned at the front. Now, I have full engagement.

Click on my '64 thread below, and look at Post #105. It has a detailed explanation of how I did it.

chevyrestroguy, you are 100% correct, it was your post that I saw the work done. Thanks for posting the number so he can check it out...Jim

when I rebuilt the front end on my 67 all four brackets were loose and the locating pins on the front brackets were sheared off. I replaced the rivets with grade 8 3/8" bolts since the 9/16 head fit the shaft perfectly. I did have to put a 1/8" spacer under the front bolt for more engagement & I faced about .030 off the head of the rear bolt.

when I put in my new spindles I'm going to pull the control arms and drill the shafst for both pins like chevyrestroguy did

Thanks for the info guys... I was thinking you would be able to skip the rivets and use bolts...
