Removable storage compartment door

Enlarged the fuzzy picture to blurry :)

Sounds like what your describing-pic later year.
If the frame is symmetrical should be able to rotate, might still be easier to drill out hinge and rotate just the door without breaking frame lose. Or adding the additional latches to make a plug in door,
if door wont flip up to get clearance you need.

Be nice to get actual dimensions of the unit though and verify it will fit YOUR box before going to the effort.
