Not sure how posting here could help you, but my experience is this:
I had an accident that took out my bow pulpit. The local boatyard had a local metal shop build a new one.
A year later some bozo T boned me while I was at anchor and I needed yet another new bow pulpit. I went to a different yard who had one built with much better metal (it didn't startimmediately pitting and rusting!!!).
You should consider asking locally. Also, IIRC "Railmakers" made the OEM pulpits and pushpits, I think they're still in business, but don't know for sure.
Finally, all MkII pushpits are not identical over the years - the perch seats changed, so be careful about those.

Good luck, happy hunting.
