ahhh good ol fridge white hehe
ahhh k got your abbreviations now lol
model changes... now you have a tricky one there hehe.. there are quite a few model differences..
ma70 chassis is 7mge/7mgte = 3lt non turbo or 3lt single turbo
ga70 chassis is 1ggeu/1ggte = 2lt non turbo or 2lt twin turbo
86 in the US is always non turbo... it has black/dark grey moulding with i think 4 like stripes which are a light grey, the windscreen jet washers are only about 5mm long and quite roundish compared to 87's which have longer ones and a little more squared
also on the dashboard you should have the rear demister, hazard switch, and parklight switch... if you don't have a parklight switch then you either have an 87 or an 88
now to tell an 87 from an 88 is also in the washer jets as they will be different... 88's will be the same as 86 short stubby ones
the moulding is totally different to any other model.. it's quite hard to explain but well.. on other models if you run your finger over the moulding you will feel the pattern... 87's have perfectly smooth moulding and the pattern is inside where the like clear cover moulds over it.. if that made sense at all hehe
87's are widebody.. guards flare out more than the others, aero roof (lift out roof) have a coin slot in replacement of the park light switch
the supra you saw was an 89+ supra... they had steering wheel changes in that year... if that supra is still at the junkyard see if you can get the loom that was plugged into the indicators.. that is what runs the cruise control etc... but unfortunately i don't have a wiring diagram for all of that
the 89+ had different indicator switches... smoother than the older ones
diff steering wheel
i believe burgundy interior was abolished?
the turbo variant from 89+ is 2hp more than the 86-88
they had two coin slots on the dash as cruise control on switches were moved to the steering wheel where earlier ones had the "on" switch on the dash then set cruise and cancel on the steering wheel
the bumpers and taillights were changed in 89.. quite a popular thing to do is upgrade to the later lights
and of course they added the great cup holder lol... although how you stop the center console smashing your straw to bits i'm not sure yet hehe
there's most of it i think... well the obvious anyway
