I've been looking at buying a 30' 973 header and have 3 to choose from. What problems do they have and what should a guy look for? Two of them have extra bracing on the main frame with what looks like a factory update.The one that is probably in the best shape and the best deal has't been beefed up there.Was that a weakness and one to stay away from.I'm supposed to let the dealers know by Tuesday what I'm doing.
