w/o jacking the car up and measuring.....does anyone happen to know what the rear LCA bolt diameter is?

 

there's a sholder on one end of the bolt, are you asking the thread size? can't replace it with a hardwear store bolt. i tihnk it's a 12mm bolt

 

was looking for shoulder size...the diam. that is goes through the bushing.

 

GM still sells that bolt...it was a little salty when I bough mine last month but it was like $1.45 a piece.... They stocked them at the local dealership as they tend to rust up and are usually replaced whenever they do suspension work... COuld I have found a supplier for the bolt to get it cheaper??? Yeah probably...but it was not worth the waste of time over 6 dollars worth of bolts...

hmmm I replaced mine with 1/2-13.
12mm hmmmmmm this would explain the need to tap my 1/2's in with a mallet. But you know what, the 1/2 is probably a tighter fit and might provide less movement...
I used 1/2-13 on the whole rear end grade 8 of course.
