So what is the final answer on the 69, does it sit back from the drip edge like the Camaro or no? I always thought they both did.
Are you talking about the vinyl top not touching the side drip mouldings? The 69 Camaro was different than the 69 Firebird. On the Camaro, the vinyl top was about an 1" short of the drip moulding, and they used a chrome strip. See 3rd and 4th photo down:
And you just solved the trim question/problem. It does look like the 'four piece trim' would be only for the Camaro. Isn't it great you have to figure out what the vendors have for sale? Since they can't tell you themselves.
