I mentioned the other day having seen an engine where a person had drilled holes and set little machined nails or brads. Well, I finally found buried with the notes I made at the time. I had forgotten I was also comparing the machined areas in two situations to see if the neoprene seal could have been used in this case (the one with drilled holes was from a 235 from around 1952). In this case, yes...my notes show the machine work matched and was centered with the crankshaft. The seal fit fine.
But please take a look. In each image you'll see 3 drilled spots. There were 6 little pieces to restrict movement of the rope seal. That in itself would have naturally prevented use of the rubber/viton/neoprene (call it what you wish) seal but it would have fit in the earlier 235 in this case. Anyway here are the little no-shift doo-dads I mentioned.
