hey champ, yeh you can fit 17s on there if you get the right offset,i have a set of roh 3 peice with 225s and they don't hit the strut and i don't even have spacers on there,granted its on a 86 but I'm fairly sure there isnt much difference,owning a ke70 as well,i even had a set of 18s on my old sprinter,i may be selling the 17s if your interested with almost new tyres hoping to get round 600,i just bought a new set of 15s, let us no if you need any further help....
