UPDATE: More DJ-3A carb info here:

On Thursday evening I spent time moving parts from Patterson’s stock, but tired,  DJ-3A engine to Rusty’s rebuilt M-38 engine so I could install it in Patterson. One item that caught my attention was Patterson’s DJ gas pedal linkage versus Rusty’s. Patterson’s appeared stock, while Rusty’s had a modified pivot point, probably the result of using the M-38 block. I decided to keep Patterson’s as it was and recreate the part for Rusty’s engine.

DJ-3A gas pedal Linkage: The linkage goes through the firewall to a pivot point on the driver’s side. When the gas pedal is depressed, a rod pushes an angle piece around a pivot, forcing a second rod upwards to a YF 2392S carb, causing the gas flow to increase.

Patterson’s real pivot piece (and it seems I misspelled carburetor in my pic).

This shows the piece after removing the parts. The pivot bolt is solid on the end with a hole for a cotter pin.

Example of what I removed from Rusty (bottom) and the bolt I will use to make a new one (top with new threads extended up it so I can add a bolt). The biggest problem with the custom piece at bottom is that it had no cotter pin. It was only held on by a bolt, which could have easily have come unscrewed as the gas pedal pivot piece moved back and forth.
