ebay maybe but their sought after. i think repros or nos could be found. maybe try Domi Racer in USA or british spares in NZ or draganfly motorcyles in UK. they would be the best chances. i just had the seat done on the B44 GP. we supplied the original cover and clips for the bloke to use/copy along with the painted base. he then brougt it back to new with a new cover with white edging and new foam exactly like original. cost $310 but it is a fantastic job and not a cheapy job. i will put photos up in GP section when i get some photos taken.
