Hi, folks. I have a Technal contact printer, one of the steel ones with the hinged glass, which I bought in the early '70s. It's time once again to replace the open-cell foam pad that covers the steel base to press the paper against the negs when the printer is closed. The last time was about 14 years ago, and I recall having found a self-adhesive one. It's about 3/16" thick (or was...). I'd appreciate a recommendation for a supplier.

Thanks.
