NP200 output shaft questions

I have a couple questions regarding the stock NP200. I had resealed the one input and three outputs a few years back, but when I finally got it on the road the I realized the output for the parking brake is leaking still. I pull it apart and reseal again, but this time realize there is a groove in the shaft. So I find a NOS one (well I thought I did), but it turns out that that output is slightly different from the others and difficult to find.

Question 1: How well do the Redi-Sleeves work and what is the part number. I’ve researched and gotten some conflicting info on the part number
Question 2: When driving in new seals, is SOP to drive them all the way into the boring so it bottoms out, or drive them until they are flush with the boring.

Any advice/help would be greatly appreciated. Thanks

This is the best price I found on the sleeve, I did all 4.

I drove the seal in flush with the outside of the bore like the original was. The parking brake flange was a little tricky as the sleeve had to be pushed on beyond the end, take careful measurements where the wear groove is so your sleeve is centered on that groove.

Thanks for the info.
