TH 350 Slip Yoke Sleeve

I had an issue with my drivetrain and having it replaced along with the tail shaft bearing and bushing. I noticed on my output shaft that I have the sleeve one there. From what I understand the sleeve (and O-Ring) are there to prevent the old style slip yokes that have the holes in them from leaking into the tail shaft housing.

Being that I am replacing my driveshaft and it will come with the sealed slip yoke with the missing tooth, do I still need the sleeve on the output shaft? If it's no longer needed should I remove it or can I just leave it where it is because I hear it's a pain to get them out.

Transmission is a TH350
