I honestly dont know how many were made but i own a 89 camaro with t-tops sorry I wasnt much help on your question tho. I currently own an '89 camaro with T-tops and know that there was a production of a mere 184,000 camaro's in all and about maybe about 15,000 T-Top production cars were made that year.
Almost 75,000 2010 Camaro's have been made. The Camaro made it's come back in 2010. The plant that the Camaro is built at is the Oshawa Plant.
It depends on what engine is in it, what gears is in it etc... theres too many factors
20,302 Z28's were made in 1969
3: 1967, 1968, 1969.
There were 5,329 1991 Camaro RS convertibles built and 3,203 Z28 convertibles both having 8 cylinder engines.
What ground are you talking about, main ground is located on battery to chasey or to engine. Other wise there are many grounds on this vehicle.
