I assume you mean lower the top and not "party down". If you want to lower the top on a 68 Camaro convertible you must sit in the drivers eat and reach up above you near the top of the windshield and grap the little handle. There is one handle on each side. Flip the handle from lying flat to sticking up. when both handles are flipped you should be able to push up the top and fold it backwards (on a manual top) or flip the switch and watch it go (on a power top) If you have a power top with a non working switch or motor, there is a chance that the top could be stuck in place and would require some muscle to move it.
