Our records are thin on this one beyond the basic catalog line, and it doesn't show up across a range of other listings we track, so we don't have extra fitment detail to add. If you're matching this against an existing gearbox or engine build, call the shop and we'll confirm it's the right one before you order.
The old alias I33A is another number this same washer has been catalogued under, so if that's what's printed in your parts book, you're in the right place.
