I had to weld up the bottom mounting hole on my radiators and drill and re-tap them about 1/2" forward. I then bowed them forward a little bit with longer radiator braces that I made from aluminum strap. Be careful not to push them too far forward that it pinches the hose and restricts flow between the radiators. The space is tight in that area for sure.
On the airbox, I used a 1996 KX500 airboot and made a aluminum plate to fit over my 250 airbox. I attached the boot to the carb, put the subframe on, marked the aluminum plate for the bolt holes, and cut the hole out so the boot mounted to the aluminum plate. Here is a rundown of what I did:

If you get a chance, post some pics of your project and the issues you are having. I know there are several guys on here that have done the 99-02 conversion and should be able to provide more feedback. Here is a guide to posting pictures using photobucket.

just an FYI...if you already have pics posted on the internet...i.e....like on another forum...you don't need to use Photobucket, you can just transfer them right on here using the "Insert Image" icon....much easier.
