Good Timing.

I got over there yesterday. I got a few pictures but no tools so I didn't take the levers off to compare them. I am hoping to go back today. I was wrong about a locating tab that limits the motion. There wasn't one. After looking at the link you provided I think that those are the same parts. It should swap over.

My set frames are bent, not from the factory they are just bent from heavy use, so I can not definitively tell you that the frames are left right specific or not.

What I forgot to do was to check and see if the inside frame of the seat back has the pivot and mounting holes for the latch and side covers. I am going to try to get over there today and do some more dissection.

So far it looks promising for a swap.
