I picked up a used set of aluminum 496 upper and lower manifolds to use for a little while on my 502. Does any one know of a part number for the bottom bolts? I know that there are 2 different sizes, a short, and a long style and that I need both.

I don't plan on keeping these for long, just until I can get some Bravo tails for some sport tubes that I picked up.

10-40011151 m8x35
10-40011158 m8x70

That is both of them.

Hurry up and get them on!!!!

those are the ones that I ordered, but they look too short? I'll have to take a pic

Uh...I hate to bring this up but your 502 uses 3/8-16 bolts not the metric ones. You need to ream the manifolds so they accept the slightly larger bolts.
