Hey guys, the guide pin bolt on my rear disc brakes backed out on the highway earlier this week. I'm having a hell of a time finding a replacement. It's the bottom guide pin bolt, the one that is torx/allen. All the kits I find just have normal bolts. Any help with this would be awesome!

The LT1 F-body rear calipers have slide bolts that look like this. Wagner H5059 OR Dorman HW5031.

I thought the bottom guide pin bolts were different because of clearance issues inside the parking brake harness?

Let's confirm it's this bolt, #45 you're looking at. GM part number 18034577, ACDelco part number 18K203. Two per side needed, sold in pairs.

Number 28. Notice the difference between that that guide pin bolt, and the top guide pin bolt.

OK, I found that bolt in the GM parts guide.

GM part number 10112649. GM calls it "BOLT-RR BRK CLPR ANCHOR PLATE & BRKT"

I don't think it's considered a guide pin or slide bolt.

Thanks! This was really driving me crazy!
