is there anyway that I can identify it from the outside?

 

and what diff did the wagons come out with and panel vans?

well, you can read the plate in the engine bay, but these cars are getting 30+ years old now, so who knows what's really in there. it could have died and been replaced with any old diff from the wreckers once or twice or more times by now

checked both my rollas, and can't find where it says diff ratio, it just says 4spd manual on engine plate...

 

on the sedan I think it is a jap diff (unbolts at back) any idea of what ratios it is?

 

does anyone know which cars came with which diffs (pref. ke30 and ke55)

 

and did ke70s share driveline with ke55s?

no they didn't. count the teeth
