For anyone who is interested, I just replaced my tired old rear coils with new MOOG CC611 coils originally designed for a 1977 Cadillac Fleetwood. The lower spring pad needs a little very minor re-work, but I gained 3 1/2 inches instantly. They are also 1/8" larger in rod diameter than the LeMans OEM coils were. I haven't tried to install my KYB gassers yet but the height is exactly what I was looking for without having to go the stupid airshock route. It really is a nice look. Now I have to install my new Moog front coils. Maybe my height will no be as noticeable once they are in. Bounce is considerably stiffer as well with the bigger diameter coil rods. Just my experience for anyone looking at a similar upgrade.
