A couple weeks ago I posted some pictures of a Wayne 60S light manifold as a surefire way to identify the pump, as it is specific to that pump only!
There are also a couple other tidbits of information on 60S parts that every one may not know. The Veeder Root will have an enlarged gear assembly on the bottom, so as to allow the driveshaft to be centered in the base of the variator! (see attached pic) This is different from all other 60's and is specific to the showcase model only.
Also the face bezels will have a curved lip on the bottom, instead of the flat one that normal 60's have. This is to allow room for the top lip on the door to shut properly and the only place I've ever seen these bezels was on a 60S, and I have seen a lot of them!
I hope this helps all of you when looking at a pump that you are questioning!
