Well, I guess I let the bolts go with the control arms as I can't find them anywhere. Sorry...

The stock LCA bolts are 12mm flanged head 10.9 grade, they are different different length for the front and rear bushings. I don't know off hand there lengths. The stock nuts are a flanged head, distorted thread locknut, also called prevailling torque nuts if I remember correctly. They are still available from GM #11515744 but are salty.

You can buy the bolts at McMaster Carr, 10 to a pack. I've bought this style bolt from them before.

The Spohn kit has everything you need, except the bolts use a flat washer instead of the flanged head bolt.
