What will kill you is the cost of shipping over all the bits. You won't know what you really need untill you get in to it. I can help with NOS engines, wheels, tracks etc. If you have the money it will be worth filling the container with everything you might need. There is a guy over in the US who bid on all the CVRTs in a tender sale once, and won them all. He didn't realise they were all partially stripped, needing engines etc. As for restoring a CVRT, they are fairly easy, have a look at my website.
