I'd think the ud find that all the DTR's from 1989 right up to 2000 would work as they are all the same clocks but some in KM and others in MPH. Or take the clock off and change the insides like a new counter and stuff im thinking about it myself getting them clocks looking more white with a blue dashlight to make it nice a blue when its dark.
afaik, the later DT's didnt come with a rev counter, just a speedo. so that makes me think they are different? id need to see a later bikes clock against mine to see if it would fit really i suppose. do they all work off a worm drive?
I reckon it would work, you of course wouldn't have a revometer so would have to do something about that. Also I'm 99% certain the brackets are different, out of a pair of each clocks you could no doubt mod a 04 clock on Why you asking anyways? The pretty blue lights? Just change the bulbs behind your clock for some blue LED's
