As far as I can work out

Q means it's soft top body
V would mean it's a van
W is a tin top with windows
K is a drop side pickup

B I'm not sure what that bit means? maybe no rear seats?

JA mean it's a comercial trim level (possibly?)

how about P?
mine was registered as a sj410P, and it's a lwb pickup, but has a flatdeck bed with a welded frame, filled in with wood surfaces, and not sheetsteel like the kja

Anyone have a clue to the L in LJ?
