I am working at mounting Clean Sweep on my Case 1250 planter, so I may not be much help.  One thing you need to check is when the row unit cycles up and down.  My Precision dealer has told me they have mounted the cylinders, with the fittings facing down, on some Deere planters.  I believe this was done for clearance issues with the row unit.  

Do you have enough brackets?  I have some of the same Deere brackets that came with my Martin C125 row cleaners and I will not be using them.
