Dave you were right !
I spent some time working on the Bird today. Both are full power but only the passenger reclines. I swore there was a handle on the right side of the drivers seat and there was.... problem is it wasn't connected to anything.lol It was just Jambed between the seat and console.
Taking a look it's cable operated though and I don't see any reason so far that the lever can not be made to work on the left side of the seat and used as a driver. I might have look in to this further.
Bones, if you push down on the handle it reclines, pull up and it locks upright. If yours is stuck, I'd guess the cable is the problem.
