Backdrive linkage
 

I have just got a parts lot with what appears to me to include some backdrive linkage parts. Only one rod has a # on it - 5630. There is a bell crank with three legs, and two short rods attached to the swivel. Closest pic I could find online is one for a TH400 BBC. I'll try to attach pics. Any help to identify would be great. Thanks, - Dale.
Sorry, says my pics are too big.
