Adam, good luck finding one of those. Its just that sort of part that drives a re-power. I passed mine onto Capt. Bill but I know his was in rough shape to start with, doubt he’d part with it.
I do have a bucket of parts that weighs in the range of 50 lbs.
It contains valve train, one or more pistons, oil pump, coolant pump, raw water pump (not sure which model), assorted brackets and who knows what else. If you are genuinely interested in it let me know. I can spread it all out and take a photo of it. You can have the contents for $100.
Shipping would probably be in the range of $75 distributed among a few boxes.
Chuck
