So here are 2 short videos (using Dropbox since Stovebolt doesn't provide sufficient upload size for videos)

1st is showing the 2 rod solution there, from the rear wheel pivot end.

2nd is showing the movement of the emergency brake pedal pivot end... tight space here so hard to get a good view. The 1st rod going from pedal pivot to the 2nd rod shown above is just at the tip of the pedal pivot bar here. The cotter pin is on the inside of the thru-hole of the bar and the bracket the rod is tied into, making accessibility to remove (or worse try to separate from rust), nearly impossible. To the right of side where the rubber is, is where the emergency brake pedal bar is seemingly welding to the pivoting bar. And to the right of it is a frame hole where the bar then goes thru with a cotter pin on the other side of it. Removing this pin, doesn't allow the bar to slide to the left as one would expect, because the welded brake pedal bar can't be disconnected (correction, I can't see how it can be disconnected). In short, I see no way at the firewall/pedal end to move the pivot bar so as to be able to remove the cotter pin and slide (or brake) out the 1st rod.

Thanks for any suggestions on this... I'm sure others have done this, but I'm out of ideas other than the heat/cool/heat/cool trick (which isn't working yet :-)
