That's right, I forgot you got them thar Fenton's on there and that frame is a bit skinnier than the AD's are. That doesn't leave much room to rearange the plumbing. I'll bet that steering box does get pretty hot. Normally of course the steering box would never see much heat at all. But hey, if the JD Corn Head Grease is working for you then by all means stick with it. I'm sure that it's gonna flow out better when its hot than it does when its cold.
