Fitted the new rims and tyres and they fit a treat! Went with the Nankang AT tyres @ 195 R15 with some replica Mercedes steel wheels from Germany. Ordered new studs and bolts from T3 Technique. Removed the small retaining bolts from the rear brake drum to ensure correct fit after the good advise on here. I think they look pretty good, new black bumpers are up next… Thanks for all the advice everyone!
