I'm still worrying the issue of lubing 39-41 springs. It seems to me that Slip Plate can replace Ford M #4682. Several of us use it to good success. We don't find Slip Plate in a tube container to be injected by a grease gun. We find if we jack up the vehicle on the frame and let the wheels hang, the springs open enough to allow Slip Plate to be sprayed between the spring leaves. Even better if brake cleaner is first sprayed between the leave to remove rust and dirt. I am suspicious of how well lube can be pushed up thru the "Extender" to the spring bolt and oozes along the depressed groove in the spring leave?

I'm also hearing that if the springs are serviced well, the car noticeably rides a lot smoother.
