The kits include the 2 sides and ends plus strip wood for the stakes. This is a very easy and quick conversion for your Bachmann On30 flats... Distress the laser cut wood sides a bit and you will have a car that looks like it's been in service for years! Each kit makes one car conversion. The boards measure a scale 12" in width, (ie. the 4 board side is 4ft tall) the Bachmann car is about 26' scale feet long.
