The problem is that the sleeves supplied with the replacement bushing kit for the QA1 shocks have 1/2" ID. So, even if I got new 12mm bolts, they would be sloppy in there.
I ended up buying hardened steel 1/2" bolts, (this time with no threads in the shear zone), and drilling out the stock shock mount holes to 1/2". The bushings are also Delrin, rather than hard rubber as the original bushings were. It should be pretty rigid, especially without the slop. I may have to set the compression dampening a couple of stops softer.
I'm just disappointed that the premier assembler of Superformance cars on Long Island let this kind of thing fall through the cracks. I'm not naming names...
