Archie makes a kit for the F40.

I detailed how I did the shifter mod on my F40 swap. The first post on the first page has a table of contents to make finding something a little easier:

Pg 7: Continued work on intermediate shaft lengthening, decklid hinge box removal and hinge modification, swap ends on DS G6 axle for use on PS, test fit modified tripod and Corsica axle for the DS axle, 4 speed shifter mod for the F40 conversion and fabricate shifter bracket on transmission, welded and smoothed DS frame rail notch relocation, smooth firewall panel fabrication and installation, intermediate shaft bearing support.


The main thing I would suggest is NOT using the getrag select cable for the F40 shift cable. Several of us have broken the getrag select cable, so it need to be made from a larger diameter cable.

Then it was time to start modifying the shifter. So back to the shelf and pulled off these shifters for parts. Two are 4 speed shifters (with each missing a part from the reverse lockout) and an isuzu.


Tore one of the 4 speed shifters down and then installed my isuzu shifter lever and the old getrag select cable. With the cable in the stock 4 speed bracket, the shifter has very limited range. The first picture is with the cable fully extended and the 2nd one is with the shifter at is full range... there is about 1 5/8 gap:



Going the other way with the cable fully collapsed vs. the shifter results in a 1" gap:


So the cable bracket needs to be moved forward. Anywhere between 1" and 1 5/8" probably would work, but I chose 1 5/16" to keep everything centered - that way I could build up the shifter stops to reduce cable abuse. Here is where I marked the section to remove:


And welded back up with a range of motion checks:





Since the Getrag Select cable only has 1 3/4" range of motion, I went and checked the needed range of motion on the F40 (the one for the 4.3) and got 1 3/4" as well, but I need to take it again in a more precise manner.

The shifter work is pretty much done. Just need to test fit in the chassis with the cables routed as they will be just to make sure everything is positioned right, then I can do all the finish welding on the bracket.

I started out with two Getrag select cables from Rodney Dickman. The cable that will become the shift cable was modified slightly to increase its stroke. Just took a tubing cutter and removed about 3/8" from the inner sleeve:



Then a card board mockup to get the general size/shape of the bracket and the approximate cable positions:



Transfer the card board pattern to some 1/8" steel, bent to shape and then use some 1 1/2" square stock, drilled some 1" holes for the cables (need to enlarge slightly more than 1") and then cut then into wedges. The round bodies of the cable ends needed about 1/8" removed (flattened so they would fit within the tubes). Then tack it all together and cut off the excess:

I do believe Roger Thelin makes all that's necessary to get the F23 trans in and a cable bracket for the mechanism at the transmission.

Roger Thelin's mounts are only for the eco tech bell housing F23 but his shifter parts do work and require a longer shift cable to reach.
Fierorog is making mounts and brackets now but not sure if he has F23 stuff yet. Dan
