59ab 80 over cam bearing

[roncol1957]

First time posting but been reading for a few years. I am having a machine shop build a 59ab for my 36 5window and got the call I needed 80 over cam bearings. I been searching for about three weeks and read all articles I could find and in one it listed NOS part numbers as 01A-6261-D and 01A-6262-D and I found these numbers for sale and I purchased. Now the boxes have D2 instead of D at the end of the part number. Does anyone know what the 2 stands for? Could it be a different ID?
