The early classic waves did not have the tramp tracks. It is possible to install them, I did. In addition to adding the track to the outside, aluminum strips need to be installed on the inside of the boat for the tracks to screw into. I took my time and got it all lined up, match drilled the holes and used a combination of 1/4-20 bolts and SS screws to attach the tracks, and of course lots of sealant around the screws.
I do love the tightness of the 3 piece tramp as it really holds the hulls together and makes a tight boat.
Where do you live? I have a classic wave that is going to be for sale real soon. It's beaten up, but it sails well and has a trailer. I'm in the SF bay area.

Looks good too:
