New Removable Top Assembly (RPO CC3) 1972 Blazer
A new (simplified construction) top is being offered to supplement the currently available (RPO CB8) top for Blazer models.

Tim - thanks for sharing this info. I had a guy from a local repair boat shop come by the house to take a look at my top.

Thanks!
Mike
