Finally! Got the AT Cooler back in and plumbed. It's such a tight fit in there, it was a true pain in the ass! But, in the end, I used some -6 AN style fittings with push-on hose style backs. Worked great and should last forever. My pops has a stash of the fittings, so I only had to buy one 90 degree end shown... lucky me since that one fitting was $14 at Oriley's speed shop.
Now this is fixed... but the pan gasket's leaking!
