this Fender matches right up with a CB350 rear fender with a factory CAB350 tag on it. that I have in stock. The only thing different is the straight reinforcing bar that the CB350 fender does not have.
It has an area of what looks to be acid drip that has taken a section out of the chrome that I have pointed out on the pictures. this area is underneath and wouldn't show Otherwise it is a very nice straight fender without dents and decent chrome on most of it.
It was marked CL350K0 when I bought it but no guarantee, email me for measurements etc before you order as all sales are final.
