Hey guys, anyone know off the top of their head what the part # is for the hex bolt? I know what size it is (12X1.5P), but I can't find one with the right thread pitch anywhere. TIA.

Home Depot doesnt have one? Odd, unless they are out, I got a hex bolt to replace the allen head one pictured above, same length and dia. just different means of fastening. Good luck if you dont find locally.

Did you find one with the correct thread pitch? I can find 1.25 and 1.75 thread pitch bolts, but none in the correct 1.5.

I'll bet if you got one at Home Depot it was the standard 1.75. I guess it may have threaded in, but you may have boogered up the threads in the head doing that.

Thanks for the help, but I don't think that's the right one.... JMX has that part # listed as this:


Bolt 11514008 engine C5 Fbody GTO Throttle body to intake manifold bolt. 3 Needed. M6x1.0x30mm

I know that isn't the right size....

I don't care where I get a bolt this size as long as I can get one. If anyone has a spare one around from a junk pair of heads I'll buy it....

Never thought I'd have such a hard time finding 1 stupid bolt.
