It's done. Barner bbrocksr wins the crocheted coffee pot. His solution worked, but thanks to all who contributed suggestions. As luck would have it, just as I finished the last little bit on the transmission, the old air line blew a hole in it. When I say old, I mean old. I bought that hose, used from Delta Airlines probably 35 years ago. (Everything I have is old.) I put the oil pan in the bead blasting cabinet and cleaned that up. It took a little finagling in some spots but I got 'er done. Now I can switch back to glass beads for the heads, intake, distributor, etc.
I have the transmission and oil pan in primer. Top coat tomorrow, weather permitting, and it is looking good at this point.
