Thanks Bill,that is pretty cheap.I also checked out GD hobbies i think there in NZ.
They have tracks for a 250/10 at $1.43 US,BUT the shipping charge is $28.00.I think i'm going
to try and fix the broken one.I am thinking about gluing a thin piece of plastic on the inside of the
tracks and assemble this side on the bottom.thi would be covered by ground work.
