To be honest, the intermediate shaft looked too short on the computer I saw this on. Def didn't see any measurements & specs.
I do remember measuring this shaft after I bought it last year (April 2021). That is when I took the "Before" picture with the MP packaging. But I can't find a record of my measurement. As I recall, it matched the spec length. I was checking to make sure it wasn't longer for certain other Milodon pumps.
