I have no idea about the steering column and it's various pieces...I do know the u-joints are TR6 howeverm but thats where it ends. The rack is a different matter though, as it's a TR6 unit. EXCEPT that the inner tie rod ends are not TR6....the 2500M items are longer. Anybody know what the longer inner rods are off? I need to find out myself as my rack needs a rebuild...it's pretty sloppy. Hence there is no table of parts on this page, but I will post as I recieve more info about the steering column itself.
