I'm looking to replace the driver's side seat's foam in the bottom part of the seat. I did a quick check on a few parts sites and it looks like the OEM ITR seat bottom foam, 81532-ST7-J21, is discontinued, however the non-ITR models part, 81532-ST7-A01, is still available. If memory serves, I think that these should be interchangeable, since both parts are 81532-ST7, and the last three digits are the production run (or something like that).
Can anyone confirm if those parts are indeed the same?
(Incidentally, if you've done the replacement and have any handy lessons learned, I'd totally appreciate it. I checked a few YouTube videos for non-integra specific replacements, and it didn't look difficult, so was just planning to tear into it

Thanks all,
Thomas
