I guess when I switched my pump around several years ago I either didn't have to deal with or didn't care about the angle on the ports. All I was after was function, and until a moment ago didn't know the different years had different angles.....

Also should mention that the pump bottom I used at the time was a new one from NAPA and the glass top was an old/original one.

Also, if you're looking foe a glass bowl pump or the top to swap check out the flea markets and swap meets. They are plentiful, and if all you want is the top it makes no difference what the bottom fits.
