I made a full skid plate for my '10 RZR LE out of 3/8th inch uhmw plastic. it is super strong (it is used to line dump trucks amoung other things) and slides over things really easily. I used a full 4x10 sheet and made 2 skids and sold the other one.
If you are going to stick with the aluminum...
I made my own UHMW plastic skid (actually two of them) out of a 4x10 piece.
It sticks out about an in on each side of the rzr and kinda acts like rock sliders.
Are these new or used bikes? If they are new won't the US dealership give you a letter?
Or here is some info I pulled off of Registrar of Imported Vehicles
