Yeah well the ol' geezer is very nearly right.
There's been so much aquisition and consolodation in the OEM and aftermarket supply world that I can't keep it straight myself, and the fact that these huge conglomerates continue to market stuff under old trade names doesn't help.

That said there are essientially 2 processes of tri-metal bearings remaining>
Clevite CL-77 and Vandervell's process.
Ford's OEM bearings are Glyco or is it Glacier so perhaps thats the same, in any case I have sat down and measured every concieveable dimension on both and see ZERO difference except the groove which holds some oil.
I am not aware from any book I have of different part numbers for different years of the 2000 Pinto block including the YB family.

Would be interesting to hear what the alleged difference are since I can see and measure none.
