GTO Moog cargo coils
 

I put some in a buddies 67 Lemans convertible and also in my 87 Cutlass Supreme. I really liked the ride quality without excess ride height. I want to put them in my 69 GTO convertible. I can't figure out much online. Anyone have any information as to which ones (part #) would be good? At present the car rides too low and bottoms out with adult rear passengers whenever there's a dip in the road.

Moog CC501 is what you want to use
 

We've put them in about a dozen various 1968-72 A-bodies and they work well.

I don't want the '4x4' look but I do like a car to sit up rather than the lowrider look of the late 60s painted magazine ads

The cargo coils won't give you the 4x4 look
 

They basically keep the back end of the car from squatting like they always do.

Staying pretty level or maybe just barely up in the back. You'll like them.
