1967 SS 12 clutch assembly question

Hello, New to posting on this forum but not new to the Sears Suburban SS 12. I have a 1967 SS 12 tractor and I had a worn clutch pivot shaft on the drive belt clutch assembly. I purchased an assembly and bracket from Ebay of which the listing stated it was for a SS 12 but no year was included. When I started to clean up the new piece I found it had a roller needle bearing at the pivot. The original from my tractor has a bushing, no bearing.

Can any body tell me if this piece is modified or if the later SS 12 tractors had bearings instead of bushings on the clutch pivot?

Thank you for the information in advance
