Car - Kouki AE86

motor - 4AGE

problem - Steering wheel isnt adjustable

question: Are the ADM and JDM steering rack interchangable and are there any differences to them besides the adjustability?

The reason im asking is because i've just bought a seat but it seems to sit abit too high and the steering wheel is touching my knee. never had a problem before cause i was using stock seat.
the mounts on the seats are bride and by the looks of it, its as low as it could be mounted.

Any knowledge would be helpful
Thanks everyone

Terry
