Tink it wa a 4wd Paul, real handy to do the conversion if you start off with a 4wd colt, everything fits, only thing that isnt straight fit is the prop carrier, think the evo one is in a different position on shaft, thats what i was saying, the evo 3 is a light car any way, and when you go and have all 4wd stuff in colt i cant see there been much difference in the weight anymore
