ok, first you have to take a picture of your rig to the county assessors where you register your other stuff (cars , boats , ect.) They give you two sets of papers to fill out. One is to verify the current vin#s on your cruiser.The cop has to sign off on this paper that he has verifyed the vin#s are correct and all match.I've got a nephew who is a cop and lives down the street so this wasn't a big deal. On the same paper you have to describe in detail what changes you've made to the vehicle.I mean what axles, where they came from,ect.,ect., Then you take that paper back and they will assign new vin #s for you vehical. Green sticker that you have to put over or next to your old vin #s on the dash. You then have the cop come back and sign off on the second paper they've given you that you have indeed put said green vin sticker in place. Take that back and pay em and get off road stickers like on your four wheelers. Kind of a long explanation. If you have any ?s feel free to call me. Phil @ 785-3184 or cell 376-0462
