Alright well I thought I knew a bit about this, but it seems this area has escaped me.
I finally got around to putting my Zenki AE86 disc rear end into my 4AGE AE71. Everything on the diff goes in fine as expected but the handbrake cables won't fit.
I've drawn I little diagram to explain.
See the small white boxes inline with the handbrake cables
Those are the mounts which bolt the cables to the underside of the body. The position of the point where the cables bolt in is too far forward (on the cables themselves) such that when you bolt the cables in correctly they are already almost tight.
Now even if you adjust the cable at the handbrake lever right out its still not right.
Has anybody come across this issue before? If so what did you do?
I'm currently thinking to getting custom cables made up.
