i took my 69 out around the block today for the first time after some restoration and the back end seems to want to sway from side to side i was wondering if there is anything to help tighten up the feel off the car?
thanks

All of the "goodies" for the later ('70-'72) GTO bolt right in. The Olds 442 got the stuff a few years earlier. Most A-bodies had it by '70. The Grand Prix/Monte Carlo/Riviera also have the same pieces in the same years.

You need the lower control arms and sway bar. This is usually a 3-piece "set".

Hotchkiss and a few others offer aftermarket rear bars. Always a good thing, even on a drag car using the "stock" rear suspension.

Replace the bushings in the rear axle case and the upper control arms. Poly-urethane bushings will tighten things up a lot. Some find them too "harsh". Stock replacement parts will work well for a decent ride quality.

Moog offers "Cargo Coils". These are rear springs that retain ride height and add about 20% deflection in the spring.

A good set of gas shocks will finish it out.

thanks alot for the ideas it will help me out alot

The "sway from side to side"s more likely bad shocks and springs, rather then dump a few grand into later year parts I would buy a good set of gas shocks and the HD springs for your car.

If you plan on sewing the cones check into aftermarket upper and lower control arms front and rear.

I hope the was a clearer answer.
