Need help sourcing T-fitting for V-drive oil drain system (2007 Moomba LSV)

[meech]

Hi all,
Hoping someone here might be able to help.

I'm trying to replace the T-fitting that connects to the block on my 2007 Moomba LSV with an Indmar 325 Assault engine. It's part of the V-drive oil drain system.

My old oil pressure switch snapped off during removal (of course), leaving the threads stuck inside the T-fitting. We weren't able to get the broken threads out, so now the whole T needs to be replaced. I have the replacement oil pressure switch (I was trying to swap this in), just can't find the right T-fitting anywhere.

This has turned into a bit of a mess, and I'm hoping someone here has dealt with it before or knows a source. I've emailed Indmar and Skiers Choice but figured I'd ask here too.
