1/2-20 and 9/16-20 are the fitting sizes on the MC....at least this is what I come up with searching this MC on the web. I need adapters 1/2-20 inverted male flare to 3/16" female (3/8-24 thread) and 9/16-20 inverted male flare to 3/16" female (3/8-24 thread). I am having zero luck with the local boneheads at the counters...I fear I may have to go to napa wh and look in their weatherhead catalog myself. I did find a dorman part #788-515 for the 1/2-20 adapter. I found on O-reiley's web a Edelman 258303 for the 9/16-20 to 3/16. Can anyone confirm these are correct adapters? Can anyone give me the weather head part numers? Any info would be appreciated. I tried searching the web but all I come up with are inverted male to AN adapters. Thanks.

disregard the dorman # above the one they had on hand was not a 3/8-24 thread. The correct number for 1/2-20 male inverted and 9/16-20 male inverted to 3/8-24 female in weatherhead are 7909 and 7910. A note here, the guy at the speed shop who didn't have the fittings did say that those threads on the MC ports can vary in size and you didn't always get those two sizes. I was thinking that may have been some of the $99 aftermarket ones as I see those are offered with 3/8-24 ports.

I'm going to sticky this for future reference and to work on getting information like this into the KC.
