Bee-R make a 34 kit for the 32 but the price is steep and shipping it from Japan would be expensive again. The R32 GTR has a great look by itself, its not really worthwhile spoiling it with a bunch of bolt on plastic parts that cost big dollars.
You'll find almost all the ODO's are wound back - you wont find a 15 year old car with under 100,000 on it in reality. Unfortunately there is almost no way to find out really how many km's your import has done. Actually winding them back is only a 10 minute job and can be done by anyone.
