Where can i get New fastening bolts for the original K-member? (4pcs)

 

What year is the car?

Here is the information for 82-90. 91-92 had different part list from what I can tell with 3 different bolt lengths listed (45mm, 115mm, and 89mm lengths).

You basically have 2 options:

Hardware store or GM Dealership.

It should be a Metric 12mm Flange bolt. It's listed as being 1.75 pitch with 115 mm long.

That's right off the GM Parts CD for Firebirds. I didn't pull the one for Camaros because it should be the same and I couldn't find my copy of it. Listed as Item 59 on the diagram it has GM Part Number 14047913. Which looks like it was replaced 01-Feb-2009 with Part Number 22603376. That new Part Number is showing up as "M12X1.75X108". So it's 7mm shorter in length. I'd say by the looks of it around $4.25 list price each at the Dealership. Check your local one though.

 

I can't help with the bolt sizes, but this thread has a picture of where they go along with the torque spec:
