Can't seem to find any info on types of fairing allowed, I see for solo's that the seat/cowl can not protrude more the 10" past the back wheel Etc, but no specs for sidecar except your hips to your shoulders must be visible from the side. I am using a wingtip fuel tank from an Avro CF100 jet fighter and it's quite long out the back with the fin, any help would be appreciated, Ray.
