I have several boxes of Disco I and Disco II parts I am clearing out of the barn. Most all of these came off of running and driving trucks and were tested and in working order when boxed up. I am posting up a link to the listings I am slowly putting up one at a time on Bonanza but can also invoice directly through Paypal. Feel free to inquire if you need a specific part.
