A-833 OD transmission what type is mine? 421,422??

The shape of the link rods really doesn't matter as long as they don't hang up on the car body or anything else. You could make them like a cork screw and they work. The shop that did some work on my car was trying to mount a Passon A855 in a 73 Charger with a 800hp 572 Hemi in it. Well it hadn't been done yet and that car has an isolated K member and trans cross member so now he gets to make custom shift rods.
One of the threaded ends on mine was bent and it snapped off at the thicker part when I tried to straighten it with some heat. Drilled it out and tacked a threaded rod in and all better now.
