I would like to put a Bimini top on the boat that attaches to the radar arch. I cannot find any info past or present of such an item for this particular year.  I can run just the camper top but don’t like the look.  I do see Bimini tops  attached to other later year chaparrals boats with radar arches. Does each chaparral & model have its own dedicated radar arch?   are there any years that the radar arches were  interchangeable ?
