Does the Jabsco "standard" larger bowl fit on the "compact" base?

I swopped bases, and found the new one didn't fit, BUT the old one was IIRC an RM69. They do look quite similar.

YES JABSCO the old large ones. I removed them both and fitted the new smaller twist and lock. The base holes were not the same-this is a fact'

Hmm, seems we are dealing with a different set of facts.
