Please help! Problem with AIR fitting - NJFBOA - Home of New Jersey's Camaros and Firebirds

Hey guys,

I'm trying to get my header project done (Pacesetter Longtubes)....I'm almost finished but am running into a problem with the drivers side air fitting on the header. The stock Air connection WILL NOT catch the threads on the header. The passengers side was hard, but it finally went. Now it goes on and off fairly easy. I have tried to get the drivers side AIR connection on for hours now, and am out of ideas. Any suggestions? I tried making the first thread on the header a little deeper with a tiny file, as well as thoroughly cleaning the threads with a wire wheel, but that still didn't work. It screws onto the old manifold fine, so I know the threads on the fitting are okay.

I feel like my only option is to clean/cut the threads. I don't even know where I could find a die around here big enough to clean up the threads (and honestly, I dont want to go that route). I'm really getting desperate...I just want to get this damn thing started!!!! Thanks for the help

Maybe go to the hardware store and find a nut or cap that size that fits the manifold and then use the nut or cap to get the threads started on the header. I remember that my AIR tubes would run out of threads before going on all the way on my 96 with the Pacesetter headers so I had to add a washer inside the AIR fitting as a spacer to all it to bottom out before it ran out of threads.

They also changed the thread sizes mid year, when I had my MAC mids, I ran into the same problem. MAC could have sent me new adapters for some crazy fee, but I just welded two plugs in em.

I'll try and find you the size.

I somehow got them on (after hours and hours of trying).....The thread sizes are definitly a little different I think. I took a fitting with the same threads and cranked it on there, and the threads got a little messed up. Either the thread size is just a tiny bit off or the coating screwed up the threads (I think this may have been the case). Why they put coating on the threads is beyond me...
