Have a 94. Discovered a manifold bolt missing from the drivers side. Last cylinder at the back, bolt closest to the firewall. Any idea of size or part number needed. Parts places all scratch there heads.

Thanks in advance.

Pull out a bolt in an accessible area that matches the bolt you need, then go to lowes or home depot and just get a new bolt the same length and size thread

GM 12552096 3/8-16 X 2 1/8 is correct I believe 9440073 is an original part number for a 2" but i don't believe that's correct for '94+

Lowes and Home Depot would be the last or very close to last choice for the "right stuff"! You should NOT have any trouble at the dealer, don't order if they don't have it's likely a 5 pack. If you're in the vicinity of several dealers just let the one you're most familiar with pick one up at another dealer for you if they will.

That part number gets you the correct flange head, the correct shoulder and also most importantly the correct physical properties for exhaust hardware.
