Hi,
I know this post has been dead for over a 2 years but figured I'd post a little info anyhow.
All the factory t-tops were done by Cars & Concepts.
There were dealer installed kits that were made by Fisher. The Fisher tops were smaller in overall size.
Have a friend that had an 85 Cutlass with them.
Those look like the C&C tops but what a bad install. There should be plastic trim inside front, rear and center,
not headliner. And they're not positioned in the right place either.
Interesting and somewhat amusing ride.
