After drinking my morning coffee, I think I would change the angle of how the cable mounts at the transmission, rather than at the Toyota gear shift. I am not 100% this would work, but it would be much easier for people to implement.
The aim is to match the throw of the Toyota Gear Shift distances to the GM Transmission shift distances:
For a 6L80/90, this is what I measured for the stock throw of the cable, at the stock cable mount location on the transmission. I don't know if the 4L60/80 distances are the same, but I would think so. In my experience, GM doesn't waste engineering time....one solution for all.
GM: Cable movement to next Gear Position
P->R: 21 mm
R->N: 11.4mm
N->D: 10.6mm
D->M: 10mm
Approximate Toyota: Distance to next Gear Position
P->R: 21mm
R->N: 12mm
N->D: 17mm
D->2: 16mm
I am not 100% certain on the Toyota numbers because I didn't write them down at the time, only made marks on my workbench, which I just measured.
But, you can see the issue.
The throw distance is the same for P->R, but different for all the others. This means just shortening the shift lever is only one part of a solution. One must also change the cable attachment angle, which allows keeping P->R the same, but changing the others.
In order to see if I can get shifting working correctly by only changing the angIe and throw at the transmission. I need to go back to the stock Toyota shift lever to test this theory. I need to order a new 3371160030 (shift lever) since mine has already been modified (and works). It maybe still available from Japan.
It will be a while before I order it since I prefer to make a multiple item order and I just put in a big order, unless someone wants to send me theirs.
Until then, my advice for those still having shifting issues, try a longer shift arm at the transmission, and change the angle on how the cable attaches to that shift arm.

Your analysis looks like an engineering research paper. How do you guys get your reverse light to work, a manual switch using a relay, tapped into the neutral safety switch??
I'm not running the safety neutral switch. Thanks

Doesn't the GM NSS on the transmission provide that?
Dakota Digital GSS-3000 can be used for reverse lights, as well as dash gear lights.
I am using Swaptime Muscle Car Module which has reverse light capability. This drives a relay.
Sorry. Let me rephrase, the reverse light on the tail lights. I got the Dakota but will get to it later.

Edited to add that one should use the Backup Terminal for powering the reverse lights, rather than the Reverse Terminal. The former can carry more current.

There are two wires under the dash if I recall that actually go to the reverse lamps. I dont remember the exact location of them under the dash.

You need a copy of your EWD. 
You can directly power the reverse lights from the GSS-3000.
Send power to pin 7 on IH1. It should be a R-B wire, but depends on year and model.
This is from a 1997 EWD.

The important connectors needed for an engine swap are located near the Toyota ECM, behind the glove box.
I marked pin 7 for you.
IH2 is the other important connector, which has most of the dash gear wiring.

This will do reverse lights nss and dash shifter indicator
Thanks for pointing this out. If using the dakota for the NSS, we won't need to use the GM NSS. This will allow more clearance for the lokar, ease of installation and it's adjustable. We can tailor the shifter throw by shortening and elongating on the arm. Messing with the adjustment last night with the 97 shifter, I was able to shift to PRND2L (+/-1/4" off). However, not able to use the last gear. Note: 92 shifter has 6 shift points (4l60e 6 shifts), 97 5 shift points. May have to use the 92 or adjusting the arm and photoshop new shift labels for the 97.

Correct no need for the gm multi function switch.
If you want to use the last gear. Just take a dremel to the last gate on the actual shifter on the Toyota side and elongate it. You’ll be able to pull it into 1st gear. You just won’t have a visual on the actual selector to see. You’ll have to go off feel
