I bought the restyled plastics for the YZ's and was going to buy a 125 to build.  Here is the thing, my buddy has a 01 YZ 125 which is mint, original everything, not a scratch on the plastic, has original tires which I would label in perfect shape except the rear has dry rotted, anyways it is like buying a showroom new 01.  I like the 01 because of the seat height.  Now I know I can make the brackets to put 02 and up tank and shrouds on, front fender and front plate is no big deal.  Has anyone ever put the rear fender and side panels on.  I have read online alot of speculation but not any facts.  Some people say you just need an 02 air box, or you need a subframe and airbox and they bolt right up?  Does anyone know for a fact if it can be done?  If I do need a subframe is it a direct bolt on, if not how much fab would I need to do?
