I was asked this question, not sure how to answer, as I am a hardtop guy,
so hopefully some can help us out,
On the convertable tops, is the frame hardware interchangable between the 67 / 68 /69 model years????
What about the Firebird tops? Do they interchange with the Camaro tops????
Thanks in advance for your answers
Rob.

Yes , yes, and yes...
Manual and power top frames are way different so don't try to mix and match, other than that you should be good to go
