Land Rover Series 3 109 FFR Springs and shocks

Hi guys question for you i am after replacing my shocks and springs, what with it being the military chassis what springs and shocks do you fit as paddocks dont list military suspension items.
Also am after fitting Parabolics at some point, will they fit straight away and again what shocks do you mount with them?

cheers

Hi
I have got rock mountain springs, nice lift, enormous load capacity, but..........
bushes failed at 11000 miles and now they won't give me any free replacements.
I have replaced 2 but the remaining 6 have failed....
Fitted their dampers. seem OK.
Miffed about bushes though.
