14BFF rebuild kit question?

[85 Jimmy]

I need to regear my rear to match the Dana 60 I just swapped in. I'm looking at master install kits and there are 2 from yukon, the ZK GM14T-A and the YK GM14T-A. What are the differences in the 2 kits? The price difference is $60 but I can't find what is different about the 2 kits.

Iirc, there are two kits based on a year model break (different pinion bearings). Basically, early = smooth housing and later = ribbed housing.

The YK has Timken bearings, the ZK is Koyo bearings

They have the 84-85 year kits with the small pinion support bearing.
