I'll have to give mine a look. I hate that foam.

I took a look at my NOS ones and they have a greenish prefilter that still appears to be OK. The gasket going up to the plastic basket that holds the pack is crublefoam as well. I'm going to try some 3/8" x 1/2" Norprene foam strip as a replacement, with polyurethane glue over the seam. The door latch and load lamp is driving me nuts. Dug out my extender card this morning to try and figure out why the driver transistors aren't turning on. Tranistors, diodes are fine, and the J9 board that drives it works in another drive.
