Default Rear spring replacement advice - 72GP

I need to replace my rear shocks, and I think this is the best time to finally replace the sagging rear springs. If anyone can post photos of their 69-72 GPs and advise which brand/PN springs you have, it would be a big help.

I think these GPs look good with a little lift in the back, but I don't want it to looked jacked up either. I've been told 70 GTO springs give more height. I've also seen comments/answers on Summit's page about the Moog "cargo" springs giving more lift than the 70 GTO springs. Based on the MOOG #s, I would not expect the cargo springs to ride higher than the 70 GTO springs.

Lengths are compressed / relaxed
MOOG #5385 - Stock constant rate 70-72 GP - 9" / 12.6"
MOOG #6319 - Stock constant rate for 70 GTO - 9" / 14.17"
MOOG #CC501 - "Cargo" springs with variable rate for 70 GP - 8" / 12.63"

Any advise is appreciated!
