I saw a brand new 1143 corn head at a dealer by the name of Skorpik in Tyndall, SD. It was still sitting on the crate like it was the day it was delivered. I'm sure he would be more than happy to talk to you about it.
Well I dont know if a 63-c corn head would work for you or not but I have one for sale I would take 1000 dollars obo for it. I am harvesting corn in Brule Ne. currently and am home for the weekend due to rain. E-mail if interested I may be able to bring it back with me when I return
