If your linkage is like my 55 C-3-B-8 (3 on tree) the levers on the transmission do not work like other non Mopars I've seen. The others also had 2 levers on the trans, but both were mounted on horizontal shafts. One lever operates 1st and reverse, the other lever operates 2nd & 3rd.
On the trans in my truck however, the lever with the vertical shaft into the top of the trans side cover only moves when you pull the shift lever towards the steering wheel. The lever with the horizontal shaft moves back and forth whenever the shift lever is moved radially around the circumference of the wheel. Inside the trans, the vertical lever moves a "flipper" that determines which gears the horizontal lever moves. Pull on the "flipper" the shift lever moves 1st and reverse. No pull on the lever, the shift lever now moves 2nd and 3rd.
I learned this while bench testing my trans after a professional overhaul that I was sure had gone wrong. After removing the side cover I discovered this "unusual" configuration.
Once you figure out which lever does what, there's only one way to reconnect the rods that makes sense.
