Holley 2245 Question/problem

I'm putting a remanu'd Holley 2245 on my 1976. I can't get the rod/pin that goes through the throttle lever (onto which the cables/springs are attached) loose. I've tried putting both PB Blaster and the 50/50 ATF/ace on it. Is there a trick to getting it loose? Left handed threads? Does anyone have a part number so I can start looking for a NOS or used one? Thanks
Tim
