Anyone know of a source for the torque arm bolts? These are the ones that fasten the arm to the carrier. The FSM calls the torque arm the "driveline support".

McMaster-Carr doesn't have metric long enough(220mm). Local sources are also too short. I show these to be M14 x 2.0 x 220. Any help will be appreciated.

Most guys refer to the "driveline support" as the c-beam. You can get used from any of the used part houses, for example vette2vette.

You must get the special GM bolt. It has a coating that keeps it from reacting to the aluminum.

Thanks guys. I'll check with the GM dealer and with vette2vette.

What special coating does GM use? Would stainless work as well? Just asking...

Be careful with SST as it's typically not as strong as the other Grade 8 or Class 10.9 hardware used. Make sure to use the same grade bolt as the original.

Look for local hardware supplier in the (online or hard copy) yellow pages or try Fastenal. MSC and Grainger are other online suppliers although I've found Grainger's hardware selection limited as compared to McMaster or MSC.

what bolts are these. are they the ones that hold the beam from the trans to the diff. the ones that go into the trans or the diff. am i on the right page. if so what year and trans. i probaly can find them at work. seeing how i am working part time at just corvettes. it a corvette salvage yard. let me know which ones you want and ill start looking.
if we have them ill give them to you. ill ups them to you. need to know soon because mon is my last day. im getting my knee rebuilt on tue.

These two long bolts connect the carrier to the C-Arm (or driveline support). The picture shows the arm fitted onto the carrier with two bolt holes open. If you can also get the nuts (2) and washers (4), that would be great!

You have a PM with my shipping details. Many thanks.

What in the world happened to your knee? OUCH!

Sorry Rich, just re-read your post. The carrier is 1995, and the C-beam is custom - but the stock bolts should fit it just fine. I think the 88-96 Dana 36 cars would be the correct candidates for picking the bolts, nuts, washers from. Thanks again.

Yes, the photo does show Banski Motorsports camber rod and trailing arm kits (box in lower right). This forum convinced me to upgrade from stock. Thanks!

well steve after talking to you fri. i strolled through the shop and found the 2nd bolt-washers and nuts. i put out for ups pick up fri nite. you might see them by mon-tue. good luck on the project.

Thanks Rich, your help is much appreciated.

They appear to be the same diameter as the rear spring bolts, maybe those are long enough. Which is also close to 9/16" which is the size of the aftermarket lowering kit bolts.

I wouldn't worry about corrosion protection, these are grade 8 or better and already pretty corrosion resistant. Stainless washers wouldn't hurt though.
