	The subject line on this one threw me for a minute Dave... For some of 
us a 1939 H doesn't use John Deere parts...  ;-)   ;-)   ;-)
	I guess that cam would be a little like an RV cam? Is that H self 
contained?  :-)  or maybe more like the old 3/4 race cams.
	Don't you love it when things go right?
