Puma swivel bearings

[Mustlust]

I replaced worn swivel bearings 6 months ago with a set sent from a local supplier. The preload was such that I had to remove ALL shims to get the correct level of preload on both wheels.
The rubber pan hard bushes replaced at the same time have perished already and I have replaced same with poly bushes.
Now, the preload is none existent. I am thinking that the aftermarket swivel bearings are/were pretty ordinary and I’m looking at replacing them….. again.
Simken make a bearing set for the bottom but I’m having a bit of a struggle finding simken top bearings. I think the simken number for the top could be NP224896.
Has anyone used these?

Timken bearing used on the bottom 606666 (lr part number)
Timken bearing used on the top TAR100050 (lr part number, this is the kit), i think if you order britpart OEM then its a Timken bearing.
Timken part number NP224896 looks right
Or was the bottom bearing used on the top.

none of the above is a given as I simply cant remember every little nuance related to defender swivels/front ends.
I normally get it all apart and go, oh its that one.
