Actually, there are supposed to be foam gaskets on the rear two hoops and rubber 90 style gaskets on the front. I ordered them, had them in hand, and liked the all rubber look better. Below are the actual part numbers. Note that all of them except ALR5548 are foam gaskets.
ALR3298 Seal rear body outer x4
ALR3299 Seal rear body inner x4
ALR3300 Seal roof mounting x2
ALR3301 Seal floor mounting x2
ALR5548 Seal front fender outer x2
