LMC has them i do not blieve they press in but are grade 8 bolts. You could prolly get them at any regular hardware store if you had the right size

The ones LMC sent me are not correct, I called them and that is all they have.
No part stores have them. Year One , Paddock etc. does not have them.
I've been on the phone for 4 hours and no one has this part.
One place said they have them but they also said it fits from 62-91 but I know 91 was not the same , so I called a GM dealer and they said no they are not the same only 73 - 87 was the same part.

Yes they do press in. the stud has splines , were it goes through the crossmember

Try a chevy or gmc dealer. They can at least give you a description or GM part number. If they don't have it in stock, tell them to search their network.

Are you referring to the bolts where the alignment shims mate to as well? If so, I am curious as well. Will eventually be replacing all the bushings and hardware over to new stuff. I remember when I brought it in for an alignment years ago, one of those studs snapped because they were so rusty. The alignment tech was able to use a grade 8 bolt. Actually did a fine job and I appreciated his efforts for a franchise store. Still holding up to this day.

I rebuilt my front end last summer and I replaced every thing but control arms and I got everything through NAPA

Might be a dumb question but are the shafts from a c20/30 bigger?
