If you go for rs250 bodywork Ian, make sure you use 92 backwards ie nf5, as that is more in keeping with nsr's,from 93 onwards nx5, ie the single sided swing arm model, just dont look right on an nsr, in my opinion anyway. If its only for a track bike why not go for chinese and get them to fill in the headlight etc, thats what i done, a lot cheaper than fibre glass and then getting it painted.
