Pop N Wood Posted December 27, 2006 Share Posted December 27, 2006 All I can say is McMaster Carr. I ordered the helicoil stuff from the earlier link and fixed the engine up right. Ordered the stuff on a Monday evening and it was waiting at my door when I got home from work the next day. McMaster Carr has a table showing the metric-SAE grade conversion listed on their site. About the only thing I did differently from the guy on the LS1tech link is I got longer socket headed cap screws than he did and used a 3/8 inch punch to snap off the helicoil tang. You don't need the special $70 tool McMaster Carr sells for that. I also ordered metric bolts with the optional blue tint to distinguish them from SAE bolts. So word to the wise, the metric and SAE bellhousing bolts are almost indistinquishable from each other with out using a pitch guage, and if you have to use more than just your fingers to start the bolt, back off and see what is wrong.

280zwitha383 Posted December 28, 2006 Share Posted December 28, 2006 You don't think it is important to use metric bolts in a metric bolt hole and SAE in and SAE hole? They are pretty damn close, but then again not really. Do you really think a cross threaded bolt will hold as well as a properly threaded bolt? Haha, please read the disclaimer... But I've been known to do some stuff that other people don't deem as safe. It's been a while since I've had an L28 on the stand but I didn't have any problems and I didn't cross-thread anything. Have you tried it? I did not buy and bolts and I remember wondering if they seriously put 14mm slash 9/16 headed, similarly threaded bolts on the engines for our convenience..... yeah right, but who knows maybe I'm just on crack and didn't use the supplied bolts.
