I am not sure if my experience with a '51 is of any help but, I replaced mine without too much anguish.
I used chrome trim from The Filling Station and rubber from Steele's. I think the secret is to let the trim settle inside the rubber for a couple of days. I used the cord method and it and it popped in quite nicely. I used my heat gun to persuade the corners of the rubber to stretch a bit.
The corners are still not absolutely perfect but, they are acceptable.
