I just bought a 58mm Holley TB off of the LS1 tech EE and the guy didn't send me bolts with it. Does anybody know the size/dimensions of the TB bolts on the LT1? Thanks much.

 

The mounting bolts? M8 x 1.25 x 65

 

Shame he didn't send you the bolts. The originals from Holley are socket-head stainless steel.

 

Sweet thanks! Yeah I know, I had a Holley 52mm that I recently parted with, it was a beautiful piece all stainless hardware. Hopefully I can find something similar from the hardware store, or if all else fails I can always see if I can call up Holley or maybe even totally stainless see if they have anything. Thanks again for your help!
