Default Inspection Port?

I feel like an idiot posting this, but...

I installed a bellhousing from another trans on my Performabuilt Stage 2 4l60e. The problem is, the circular hole on the bottom of the bellhousing was not capped on this bellhousing. The previous owner of the bellhousing must have removed it for inspection, no problem, I'll order one up. I figured it was an inspection port, so I've been searching for a replacement with that verbage... to no avail. All I find when I search 4l60e inspection port is part number listings for the two plastic covers that go behind the starter and the oil filter.

So, what's the appropriate name for that circular cap on the bottom of the bellhousing on the 4l60e and where can I find one?

I Googled "4l60e inspection cover" but only found posts of other people looking for the same part.
I would call ebay seller "powertrainpartsplus"; I have bought cases and various big parts from them. They are in NY.

It won't hurt anything to leave that hole open.

You, sir, probably don't live on the beach... LOL!

I thought about leaving it open, but man, there's just so much damned sand on the roads. I'd rather cover it if I can, and I'm almost to the point of fabricating some sort of cover that may rotate/latch in place for easy access...

I'll keep my eyes open for a spare one, but you could just cover it with a piece of duct tape.

I know this is an old post, but thought I would answer the question in case anybody has been searching for these. They are labeled as/under Transmission Bellhousing Plug/Cover.
