Upper left is the one to use.
'Funnel' shape metal piece goes into the axle tube side.
Some early axles (thicker tube walls) you will have to trim the 'Funnel' flange some to get it to seat in the tube properly, but if you don't overheat the rubber when grinding on it, it's not an issue at all.
You want that metal 'Funnel' to be as tight to the axle tube wall as you can get it and still fit in there. You usually don't have to take much off, if any!
I've done several in the 'Field' with a hand file in the past few years, so it usually doesn't take much at all.
The metal 'Funnel' is an 'Upgrade' to the seal design,
The intention is to guide the axle through the seal,
Instead of the axle chewing on, and ripping into, the seal surface.
You 'CAN' use the same old oil seal type the factory used, but they are INFERIOR to the newer 'Funnel' design.
REMEMBER TO USE EMERY CLOTH AND 'SPRUCE UP' THE SEAL SURFACE ON THE AXLE!
Go AROUND the axle so the sanding lines work with the seal, instead of cutting into it.
Old seals mean rust and wear marks on the axle, and you should try and remove rust/edges before putting the axles back in on new seals.
REMEMBER TO LUBE THE RUBBER LIP AND AXLE END BEFORE YOU PUT THINGS TOGETHER!
Don't want to start out on dry seals!
A little wheel bearing grease or gear lube is fine, and if you don't get carried away, even engine oil will work to lube the seal lip/axle end-seal surface.

That's what's LEFT of the orignal oil seal!
Yup, that seal there is all that stands between mud, water, grit and any other contaminant that can enter the axle tubes and your VERY EXPENSIVE differential and differential gear set (Ring & Pinion)....
That Warped, Rusty, Worn Out and Torn mess is the reason why I say when you have the axles out,
Drop the carrier (Carrier & Ring Gear) and change the seals!
That's not even as bad as I've seen! That one still has PART
of the sealing lip left on it!
I'm sure it wasn't contacting anything, but at least it's still there!
I've seen them with virtually ALL the rubber missing!
