[Andy_B]

I have my front end loosly (sp) together and the tracking on the passanger wheel is a country mile out...i disconected the track rod end today and shifted the wheel to about straight..not perfect but close...and it looks like i need to lengthen my extension by about 40mm !! .my extensions are 130mm in total length...has anbody else had this issue...my rack i think is from a MK2 escort M14 threads so not MK1 ..???
