Anyone own the Zedder cross reference app?

Mine is on a 20 year old laptop somewhere so I can't easily get to it.

Here's my problem.  All the Yamaha parts fiche a show an incorrect part number for the 1976 RD200C inner fork tubes.
They show 53-52312-40-00.   Most likely the part is 535-23124-something.
The prefix for a lot of the 76 parts is 535, so I've got that.
The 1975 part number is 337-23124-60-00.

If you have the cross reference app, can you tell me if 337-23124-60-00 crosses to a 535-anything?

I don't recall all the Zedder features, can you also see what they show for a 1976 RD200C inner fork?

The main reason I suspect that I can't use other years is because the 76 is a one year only front disc brake.  Not sure why that would change the design for the inner, but who knows.

Thanks
