Yeah, I previously assumed that the speedo cable had broken, but it had actually not been locked into the back of the dash correctly, hence not working. When I replugged it back in etc, everything worked sweet. Obviously it is way out due to the new diff ratio, but that is what a GPS is for (Will actually get it fixed properly by a speedo calibration joint)
Also, going to just buy an AE86 swaybar from AJPS I think. Too much effort to find an 'old' celica one when you live in a small(ish) country town.
Cheers man, thanks for the kind words. Also, sucks to see what happened to your car Hope you can get it back out on the track in its former glory again!
