Never have purchased from Rock Auto. I was researching to see if the XR5 plugs used gaskets or tapered seats to seal when I found them. Since I'm an auto parts sales rep, I'm gonna see if I can get them through my warehouse sources. Just thought you guys might want a good price before I find if I can get them myself.

Yah Rob, the XR5's are a 3/8 reach gasketed plug with a 13/16 hex. A-ok for a 69 Z28. The UR5's are a .460 reach with a tapered seat and a 5/8 hex for the later stuff.
Any time there is free horse power to be had my eyes and ears really perk up! ![]()
