I've recently acquired a lovely GT6 Mark 3. One or two issues to sort out the first being really 'vague' steering which I've discovered is due to a faulty rack to column shaft steering knuckle. Haven't had a good look yet but at least one of the securing bolts seems loose and the knuckle looks generally dodgy. Am I correct in thinking this part has been superseded by a UJ? If so, does it fit on without any other adjustments? I'm a newbie so sorry if this sounds a daft question! Second question is where do you recommend I go to for spares? I've used Rimmer Bros in the past. Cheers.
