Maybe FRC7043? Roverparts.com has parts catalogs for Disco 1. Scroll down to the bottom of their webpage and look under Resources Center, Land Rover Discovery I 1994 - '99 Parts Catalog. It shows on page 11 (Transfer Case). Those catalog pages have really helped me, even though some part numbers have been superseded by now. There are also catalogs for Series and Range Rover Classic. Rovers North also shows parts diagrams on their site. A picture is worth many words....
The Product Information for the part you show seems to say it is for the Input, even though the title says Output. Seems to be a minor mystery???

Any opinions on this?
Not the original. But found this at NAPA, shaved it down .003 and then gently persuaded it in with a socket. Slightly slightly rounded but, I think this will provide a better seal compared to the original.
Does anyone have any objections to this working?

If dimensions match it will be just fine. Just wondering about the function. Is it just a "spacer" or does it actually seal something? Or maybe the seal popped out when the shaft was installed?

It keeps the fluid from seeping out of the transfer case I believe. Should do that just fine I believe. The dimensions weren’t the same, but the rubber inside opened a bit around the output shaft. Once it was punched in it seemed like it fit fine. We will see if it starts leaking haha

The LR parts diagrams are super helpful for this type of stuff....

When possible, I prefer to use Corteco brand seals which are manufactured just a little better than many other brands. Not a complete necessity. I would absolutely avoid BritPart products in critical applications.

Looks like that diagram in the link does not show a seal inside the flange. Also appears the mud shield is installed backwards in the photo. Maybe the seal was installed as a spacer to allow the drive shaft to move back a bit due to extra lift geometery?

Not sure on the lift geometry. Have never heard of that, have lifted many vehicles. I don’t think the teeny rubber gasket would’ve done anything but crush under any pressure though. And the mud shield should go out as this is how the original was and the flat face was towards the back. I totally winged this, but it was the closest thing I could find.

MJ, Looks like the flange is bottomed onto the shaft when torqued on. The metal core of the seal will provided mechanical spacing, maybe 1/4 or 3/16 inch only. Maybe a mechanic installed it to provide some vibration absorption? Keep the flange from rubbing? To space the e-brake drum? Just a guess, but the seal you installed does not show on the parts diagram, and does not provide any oil or water sealing.
The diagram that was linked also shows an "optional" mud shield seal, positioned between the flat face of the shield and the TC. Probably more useful to those drivers who wallow through mud holes or traverse tropical dirt roads. It looks like you are following the work of a previous mechanic. For me, I have not needed to work on that flange, so just relating my take on the diagrams. The mud shields on the differential inputs face right up close to the differential seals, for functional reference.
