The original bolts were of GM #3708352. These bolts are 3/8"-24 X 11/16" long. They are GM-300 material (SAE grade and they have a captured lockwasher. A captured lockwasher is not a necessity, though; you can use a seperate lockwasher. The length may be critical, however. You can easily trim/grind a 3/4" length bolt to the required length.

No bolts of the original spec are currently available from GM.
