Slapstick mechanism pics request

Ok, so here are the pics of the first run on making a stopper gate.

The first pic is the side view. The new gate sits lower and the stops are REALLY close together due to the small radius because of how low it has to sit to clear everything ( that big square block on the shifter )

This pic from the rear shows the offset of the lower gate.View attachment Jeep_shifter_rear.jpg

The next couple of pics show the interaction with the lower gate and the gate pin. Notice the gate pin now looks like an L rather than an I and the side piece of the L sticks out to ride on the lower gate.

The gate functions very similarly to the mopar slapstick, for example:
The pin contacts the lower gate BEFORE the pin gets to the upper gate gear location, pushes the lower gate forward until the lower gate gets to it's stopping point ( determined by the slot in the front mounting point.
At that point, the gate pin can move upward to the top gate, freeing itself from the lower gate, allowing the lower gate to slide rearward to resting position ( ready for next shift )

The shifter behaves the following way:
Shift from P to D, lower gate does not get contacted by the gate pin. Button depression is required to shift out of park.

Shift from D to 2 or 1 lower gate gets pushed down by the gate pin when shift button is depressed and shifter can be moved into either 2 or 1.

Here's where it gets cool:
When shifting from 1 to 2 or 2 to D
Slap shifter = advances only one gear at a time.
Slowly slide shifter forward = advances from 1 to N just like stock.

One other side effect is that I can hold down the shifter button from 1-2 shift and it CANNOT advance past 2 until button is released.
I'm not sure if that's the way the stock slapstick works but hoping someone will chime in.

On a side note, the tolerances for this type of mod are VERY tight. If it's off by just a hair, it wont stop the shifter, or if the spring tension is too light on the bottom gate at the rear ( see pics ) the lower gate wont return quick enough.

I'm also thinking about what could go wrong...for example, what happens if the spring breaks, does it lock up the shifter? is that even possible. The answer to that is no. The lower gate falls away from the upper gate and ceases to function...but I sure as heck don't want this mod locking up my shifter....but I have lot's of time to mess with it before the car is back on the road.

Anyway, just some ideas for what I think is pretty cool.
