Yeah, I knew you'd have to take the down pipe loose again. I'd try the bolt first with the adapter still in place with the old gaskets, to do a test fit with the down pipe to see how it goes. Save the new gaskets for the final installation. If it were me, I think I would heat and ding the down pipe if needed, to get good clearance on the bolt head vs cutting the bolt head. That bolt is worth what the dude is asking for the kit!

It's a bit of a pain in the *** to get those down pipes out. You the torsion bar has to come out and even then it's not fun. I was hesitant about the ebay bolt because I'm not sure it's gonna clear, but dinging the pipe is maybe not a bad idea. If that bolt actually improves oil flow - even better!

@66fyssh At some point I the adapter wasn't dripping one bit, but then I repositioned it for dumb reasons and it dripped just the tiniest bit, but now that I repositioned it again to make the new transmission dipstick tube fit, it's leaking more. I can't get it tight, I tried the adjustable wrench and even cut a 1-3/16" wrench in half to make it fit through the suspension etc, but I can't get it tighter.

I never want to have to take that adapter off again, so I think I will get that ebay bolt and tighten it until it's leak-free. It currently leaks when I spin the oil pump with a drill, so that's a good way to test it.
