Anybody aware of where they might sell the oil pan. I have a 78. O'Reilley's is a no, rockauto no, eBay, ect... i'm guessing I'll just have to drill in a new drain plug.. I also looked for just "20r oil pan" found 1 that's $150..
Expand your search, 22R pans bolt up to the 20R just make sure you have the correct pick up tube for the pan
