Needing new fork seals, I ebayed some called "leakproof". What I got were some loose fitting all-rubber pieces - not at all like the seals I removed. These had metal housings with springs wrapped around the back side - what I would expect a proper fork seal to look like. There's a youtube showing how to silicone the all-rubber seals in place, fitting loose as they do in the fork lowers.
Do these cheesy looking seals work - or did I get the wrong part for my '73 T140 forks?
