Exclamation Please Help! C4 transmission will not fully engage in park?

Thought I'd post this in a new thread. I'm having a problem with my transmission. It doesn't want to fully engage park. I tried adjusting the shifter linkage to no avail and I discovered why when I was working on my u-joint problem. It appears to me that this transmission may have been pulled out of a console shift car. Follow me from the auto shifter to the transmission... the auto shifter drops through the floor and connects to this z-bar, this z-bar travels towards the front of the car and connects to a "little arm" that rotates on an arc and dissappears into the transmission. This "little arm" is incorrect for my car. I looked at a stock 66 up on a lift and got a good look at a correct setup. The little arm in question on the correct car is orientated up and down when the car is in park. It travels forward on it's arc when shifting through the gears (pull the floor shifter to the rear, the little arm travels forward). On my car, the little arm is about 3/4" shorter and is orientated left to right when in park. I believe the little arm needs to travel downward on its arc a little farther in order to engage park. As you all know, the auto shifter linkage travels left and right, not up and down, so it can not travel the rest of the distance to fully engage park consistently.

An additional problem I'm having with this little arm is the fact that is shorter than the original arm and therefore travels on a smaller arc. This explains why my car shift so quickly. My floor shifter reads nuetral when it is actually in drive! I obviously need to get the correct little arm, hopefully it's an easy fix.

My questions are...

1. I understand that the C4 was used in several cars. Can I just swap out the little arm with the correct arm for my car without having to worry about the internal workings?
2. Where can I get the correct little arm? Is it something I can order or do I need to find a donor car?
3. Has anyone else encountered/heard of this problem?
4. Why do people choose to cut corners on such simple, gorgeous vehicles?

You are correct on all the above. I have had the same problem on my 65 and I took a C4 out of a Falcon and robbed the trani parts with no problems. The only thing with the trani is watching the springs and check balls. Make sure you know where they came from. But you should have no problem switching parts. Junk yard for parts or NPD.
