Hi all i have some more info that has come up latley , im on to rack number 4 a holden barina power steer rack , it is the closest one to the right length of all the ones ive found , still has to be shortened but i dont have to remake the rack shaft so i modified the rest of it in a day and am now mounting it to the crossmember, it has a slightly slower ratio than the mazda one i mentioned earlier but by only 5mm per rev leaving 45mm of travel per rev this means 2.5 turns lock to lock , plenty good enough.
