Katy, a 3-on-the-tree was the standard manual transmission set-up for base Camaros (either with a V8 or a 6 cylinder). If you paid about 50 bucks you could get a console which moved the shift to the floor. Camaros like yours are now nearly impossible to find because so many have been converted into more desirable Super Sports, Z28s, or hot rodded. Many people are now looking at early Camaros as investments or something to drive to shows on weekends, and original examples will keep their value (and may increase faster than ones that have been modified). I think you should keep the car as original as possible and sell it if it's not what you and your husband want...then go and buy one that's already been modified. Cars like yours seldom show up on the market because there are very few of them left to sell.
