Newest ISS part number?

[tsb09000]

I know there are quite a few Intermediate Steering Shaft parts numbers out there but does anybody know the latest and greatest? Hopefully with any and all kinks worked out of it. I might be replacing mine soon but want to make sure which one to order.

Anybody?

The more I think about it, the more I want to replace mine.

I just hate to end up with a 'new old stock' older design still sold as new.
