Hey guys, thought I would share my experience with this issue and what I did to fix it. My clutch and brake pedals were making intermittent clicks. Checked my firewall welds and one of the top two were out and the other one was going out. I bought the following items:
Vented hex bolts from Amazon for ~$7 (any type (just not headless) of vented fastener would do - i just got what was cheapest then)
Mechanics wire, red loctite, and clear sealant from Harbor Freight for ~$8
Washers and nuts from Home Depot (I got stainless - probably not needed though since the sealant is slathered on everything) ~$5
It's the same idea as humble rumble's kit for installation by using the mechanics wire to fish the vented bolts through the hole. I did do the extra step of Dremeling a slot on the end of the bolts so you can use a flathead screwdriver to keep it from spinning when tightening it down. Also, I just used regular flat washers and red loctite on the nut. No more clicks after the install.
