Well, a small updated. I mentioned I did this before, but never posted pictures. I tore the foam off the back side of the block. The reason being is that I need to attach the cabinet catchers somehow and they're not going to attach well to foam!
I'm not exactly sure how I'll attach the pieces yet. My one thought is to just fiberglass the metal piece directly to the block. The other idea is to fiberglass small blocks of wood to the block and then screw the metal pieces into the wood. That makes them replacable if they rust or don't work or whatever.
Peeling off the foam leaves a very rough surface.
The cabinet catches are going to need to be modified to mount them in the grill. The one on the left is how they come from the store. The one on the right is mostly modified. It still need a couple holes drilled if I'm going to use screws, and the slotted flanges need to be bent up to hold the rollers somewhat in place.
