Smooth as butter. I should have done it a long time ago.
I swear it wasn't exactly easy though just based on trying to contort your body and arms to reach up behind the dash in the dark with tools and unbolt/rebolt a couple of bolts while keeping the rubber gasket on the back of the backing plate not move around and obstruct the bolts so you have to pull it down and start again.

Thanks Cdan for all the parts.
