1960 PG Tail Shaft Part No.

[Joe M.]

The photo shows the part number on my PG tail shaft. I cannot find the part number in the GM parts catalog. Is that because it was part of an assembly with another part number? What is the correct part number for cast iron PG tail shaft? The image is upside down.

update: I researched more and found out that the number on my tail shaft is the casting number, not the part number. That is why the number did not turn up on parts search.

That is NOT a shaft, it is a housing.

Joe-
Correct casting number for the extension housing is 3726595.
