I'm not totally sure (have to check) but I think I have a used set of 10.9 grade bolts for the LCA's and Panhard bar by UMI performance. They are 10.99 a set off of UMIperformance.com. I can do 15 shipped if you are interested.

The lower control arms will use a M12x100mm grade 10.9.

The panhard bar bolt is a step bolt that steps from a 14mm shank to a 12mm thread. This bolt would need to come from a GM dealer or reuse the stock one.

I hope this helps,
Ryan
