A word to the wise about dryer seals

Replacing the rear felt seal has been more fraught than I expected. The video explaining how to replace it claimed it only took a few minutes. This is so iff there's no old adhesive to clean off (Goof Off worked, but it took elbow grease) and the replacement seal just drapes neatly around the drum. I had to clamp and stretch and reclamp and restretch to get the new seal into place.

A different video said use 4 clamps. I'm using 3 large ones and about 20 small ones, and am going to wait overnight for for the felt seal to "relax" into its new length before I try to glue it on. In the meantime I'll get a few more strong spring clamps (they'll also be good in wood work, so won't be a waste) before I start.
