Kinda obvious really, you need the 89+ seals, although you could save yourself some money by using weatherstripping from a NAPA and just putting it around the area. I bought OEM for about 34.00 if I remember correctly. The pre 89's are very similar (may be same with slight difference for holes) but if you are buying new, get the correct ones.
If I were redoing my seals, I would just make them myself at this point, but if you do a continuous tape, I suggest you put the "joint" at the bottom of the light to prevent any seepage at the top.
