Btw, I was surprised to see there is now apparently a really correct repro oil pan, Scott Drake makes a 5 quart version of the C5AZ-6675-BL for 64-69 that appears to Not have the kidney dimples (the impressions that most repros have on the left and right rear sides). I had to look for a long time before I found a decent used original part to modify. Some really talented guy generously made this drawing for the pointer a few years ago, I won't name names, he may have the copyright .
Repro bell housing spacers are cheap and available, in case yours is scraped. Since the tranny and the engine may be mated for another 50 years, it may be a great opportunity to powderpaint these and have them in place forever....
But plan B, if compression is still lively in the engine and the only issue is a freeze plug...or if your guy can get the work done before Spring weather and get you back on the road, all is good...Lee
