The chevelle piece will definitely fit,but I was not sure how rusty the actual glass channel was in the pic. It may be easier to blast the rust and see what is left. The pieces that are available only cover the lower windshield area and do not go into the actual dash ribbon seal area. On the 64-5 cars,that part is a continuous piece with the dash as Loren stated and is glued under the lip. IF one is lucky maybe that glass run area is better than it looks and cleans up ok. There is of course always the option of blasting it and doing a fiberglass repair. We sometimes frown on repairing like it is 1980,but I think it would be a good alternative. The corvette guys might rag on you,but their whole car is made out of the stuff.
