I am working on restoring my Super 77.  It had the Car-Lynn power steering Torque Generator on and I am hooking it up to a GM power steering pump.   I built a bracket and am using the two 3/4&quot; bolt holes in the fram to mount my bracket on the inside of the frame.   The pump will stick out about half way.   With the Super 77 open covers this will not be a big problem.  I have tested the system with a drill running the pump and it appears to work.   Won't know all the details till the tractor is running again.  Am also adding a 60 am Ford alternator and electrical system.   Just finished painting the basic frame today and will start reassembling the tractor soon.  Cant wait to see how the powr steering works.   Have herd talk on other forums about this set up so thought I would give it a try.
