Cl160 exhaust collars/shims

I've managed to track down everything on my laundry list of parts except for the exhaust collars/shims. Stupidly purchased a NOS set of cb160 exhaust collars that have shims built in but won't slip over flanged ends of the scrambler headers. I'm happy to trade the cb160 exhaust collars or simply pay for their cl160 counterpart.


Thanks in advance!
