Is the old gasket a really odd shape that using some generic grommet is out of the question? If so and the old gasket is in good enough shape that some Bondo or hard sculpting clay can be applied to fill the cracks and replace any missing chunks you can do that and then sand the old repaired hard piece smooth. One you have it looking decent you can use the old piece to make a silicone mold and then use urethane rubber with a UV stable additive to make a new piece. I have done this for a few odd pieces on the 47 that were unavailable. Here are photos of those basic steps for some sill pieces I made.

For those that spot the differences, my 47 originals were so bad with large missing chunks as to be unusable for patterns so bought used but slightly damaged 48 pieces for the starting shapes. Those are different cosmetically from 47s so this job actually had another interim casting after the cracks and missing rubber in the 48 pieces was repaired. Using plaster of paris a work casting was made duplicating the repaired 48 pieces. That plaster piece was then modified to the 47 cosmetics and then a second silicone mold of that modified plaster casting was needed to make the urethane repro of a correct 47 sill.
