Here's my experience (72SE):







Removed the old seal, the new seal slides in and this little metal tab goes through the whole in the rubber seal. Used some silicone spray as the seal was a very tight fit; which of course you want.


As we know with most repro parts they are usually a little off, the hole that was drilled in the seal was out of place so I had to drill a new whole and it had to be a little more oval for the rubber seal to fit over it.


Finished product, I am very happy with it and glad it was available in the aftermarket, mine have always looked like crap.
