Best fix here is weld a round cover on the pan and use a 1/2-20 GM drain plug welded in the center!

We've done a number of these to date!

Thanks, Gary in N.Y.

P.S. Here's a few shots of the fix on a more recent build! If you look very closely this one also has our dipstick-adapter installed to make it "removable" without dropping the pan. Easy to change the adapter gasket if necessary??
