Hmm, I bought (4 years ago) the OEM "brand" panels (same?)and the only trimming I had to do was on the L shaped (? rear 1/4) moulding to get the door to close. I have the latex rubber on now, and all is good. The pulls seem to be fine and the fasteners seem to grab. Do you have a photo of the back of the panel...wonder if they are the same, mine had a yellow foam back if I recall,
