Spent Friday night and Saturday morning installing the lost plastic with the Pinbits board and their plastic protector set. (Thanks Pam for the fast shipping and adding the forstner bit. That was very helpful...). Pretty much remove the whole back section to get the back off to install it: all ramps, POA, etc. Great excuse to clean back there but it already clean. At least I can say I put some fresh wax down.
Looks great and like everyone says you need to fine tune the locking pin for the POA to have it working consistently and not getting bound up due to the plastic thickness. Added some frosted warm whites to the GI at the back areas and Pinbits rope bridge light board.
