Spring confusion

Good afternoon everyone. Well an mot fail today but not to bad. All flex brake pipes need replaced and front spring on drivers side.
But what springs? I want to keep std but what was std on an 03 disco2 with 7 seats ace and air. GS model.
The colour codes have all but gone on mines. Pass side has hints of orange. Drivers side looks grey but they could be faded.
Craddick list a Green and orange 9nly for RHD 03 onwards but I called and they weren't that helpfull on which one I needed for the drivers side. Listing yellow and purple, grey and purple or yellow and orange.
Discuss please, and help me get my order in so I can get the beast back on the road. Part nos would be a help if you have them.
Thanks in advance.

See this Front springs

Sierrafery I had viewed this already but my colours if fitment differed from the combinations. Which isn't a surprise.
But would any of these combinations do? That's what's confusing me.
A mate has a front set lying that are
101340white/purple 101341white/orange britpart springs
I suspect the colours are wrong or faded though.

I'd fit REB000310 and 000320 if i was you...though wait for other inputs too

I have very similar car like yours but mine is LHD. I have installed REB000330 both sides. Works great.
