I have only seen ones for the 67 and 67 as well. It could be a new part. I would try to fabricate tabs in any event. I purchased 69rs aftermarket fenders for my 69rs camaro and they have been an enormous pain in the neck. I went this route to try to save some welding (which I do not know how to do) and some body work since I am doing the car myself. Well, I ended up needing some welding and body work to boot on brand new fenders! However, after beating, banging and welding, they finally fit within toerances. Good Luck.
