I just put new rear coil springs on my '67 C/S. I went with A/Z RCS5385S (made in USA,) which are heavy duty springs. It raised the rear end 1 5/16". Pictures show both before and after.

 

Is that what you were after?

 

The after photo looks like it should (Factory Stance) These cars had that look to them....

 

I wanted it a little higher, and I figured 50 year old springs were worn out. I may go a little higher after replacing the front coils. It will eventually have a '71 "Hearse/Olds" 455 with a TH400.

It rides much smoother now with the new springs along with the rear sway bar.

 

they sell a spacer that fits under the rear spring, i got one in a 1" size to lift the rear a bit but not change the spring rate

 

I put Moog Cargo Coils in back of my '87 Cutlass and also a friends '67 LeMans convertible and in both cases I was happy with ride height, firmness and ride quality. In neither case did the car have a jacked up look at all.

 

What is a 71 Hearse/Olds? Are you referring to an engine from a Cottington Hearse?

 

Who sells the spacer? Just put new shocks and springs on and I am not happy with stance. I would prefer it to be slightly higher
