T@B 320 -- water pump access panel - reinstallation

Hi Everyone - I've successfully removed and reinstalled the water pump access panel in the past, but it was in a timeframe of 15-20 minutes when I could remember how that panel gets reinstalled. It's tricky like a game of Tetris.

However - I pulled out that panel many months ago, and I'm struggling to figure out how to get the darn thing back into place. Anyone have a trick/tip/hint? Maybe a video somewhere showing the correct orientation and gymnastics required to get the panel back in correctly?

I would very much appreciate some guidance - thanks in advance!
