In the 94/95 FAQ section, there is a great write up on how to do this. I purchased the replacement part mentioned in the instructions and just used the plastic beads. The new assembly itself was a little different, but my original one was perfect once I cleaned it up and stuck in the beads.
I should have bought an extra replacement part, because I'm sure the other window will give me problems before too long.
FYI: I printed out the FAQ section covering this install and started the process. Took less than an hour with no problems at all.
