Hey Shawn, I went back and looked at your photo in the full size format. It is a square window so my original thought was nearly correct. It looks like a round window in the small format. Thats what through me off on guessing the year. Is there an STC to convert it or do you just move the gear. Were the original Pacer conventional gear fittings on the frame or must they be added.
I think the Pacer and triPacer were produced concurrently for a short time but eventually the Pacer version was dropped. As I said befor, many thought that the tri gear ruined the Pacer/Carribean. At some angles the pacer is beautiful.
