I have bought myself a project which I have been slowly working on for the last 6months and the i.d plate has me stumped as I can't find the info to decider it all. It is a 1971 440L.

It has the paint code Q (yellow glow) which I can't find listed anywhere for a mk2, only from 1972 in the mk3.

and in the serial number it starts CK75LL, and as far as I can tell "75" doesn't exist in the mk2, just the mk1.

i have looked and looked but can't find these particulars for my mk2. Has anyone else come across something similar or can help me? At the very end of the run for the mk2 was there some limited number (rare) models?
