While there is a thread going on this item, allow me to pose a couple of commonly asked questions concerning the heavy duty air cleaner kit. Are the round "bell" and rubber nipple still available through mother Deere using 317-400 part numbers? Also does anyone have the pattern or exact measurements needed for installation on the 110/112 hood support. As soon as I can get mine powder coated I will be ready to install on my '73 110.
