They go back to about 1983. Be careful a lot of the early ones were 4 speeds. They look a like. The is a tag on all of them that is held on by one of the rear housing bolts. There are numbers on the tag. In the bottom left is a number 1352-xxx. Take this number & find a chart on the internet. It will tell you by this number what it came off of & the gear ratio's. The Camero is a good one to use but the shifter is way to the rear. You have to have bucket seats.
