Combines 105 combine bean head

I run a 50A series row crop on the 105 without auto header control. Have the old float springs under the feeder house, as well as the 6 inches of float in the bean head, and get along perfectly just by watching the red ball and raising or lowering accordingly. Also have a neighbor w_ 95 that runs 213 platform in beans in similar fashion and does beautiful job. We have thought about going to auto header control. The schematics for 95_105 and 4400 hydraulic systems are very similar. Installing AHC in 105 would be a matter of finding the right fittings and plumbing in the solenoid valves. Dial a Matic would not be so easy.
