[Fot] Rear Main Cap

[Rod Pierce]

Based on how far off the bearing is offset, I wanted to rule out
differences in model years for the 1300.

It seems the answer to my original question is that there was considerable
variation in engines that came off the assembly line when these cars were
made.

Solid evidence of why you don't mismatch bearing caps!

Thanks for the input.
