Rover,
I don't know of any aftermarket end link solutions for the deep diver, it's not exactly got regular lugs. If you do find end links that fit, please let us know!

Same goes for the bezel insert, I doubt those options you mention will fit. I believe Squale divers (with similar case) will be a very close fit, but look almost identical to the OEM insert. Personally, I wouldn't touch it - the insert on these are super cool. You have the added problem of actually removing it too, it can't simply be pushed out from the back. You'll need to dig it out (damaging it & possible the actual bezel), or drill a small hole in the rear of the bezel and poke a tool through to push it out.

I'd strongly recommend you leave it as is!
