Hello OP, nice to see you!

Ez' after some, digging, lol, I would strongly suggest NOT pinning anything special on the following items -

The door design (standard design, used a lot)
The wreath (standard design, used a lot)
The cherub (standard design, used a lot)
The drain holes at the back (standard design, used a lot)

The Griffin and the stained glass is a different kettle of fish however.

The physical dimensions and placement for caskets also important.

This from the actual builders of the thing.
