So as my father in law and I were building and re-building his d300 shift linkage we talked about a ton of ideas on how to improve the simple lever design. I also came up with some ideas to make it more serviceable.
So since he pulled his behemoth/d300 for now I decided that the ideas we talked about were too good to forget and so I redesigned my d300 shift linkage.
The goals were to;
be able to remove the center console without removing the entire shift lever
decrease the total number of pieces. (weld washers in place etc) so that I wouldn't have a ton of 1/4-20 bolts/nuts/washers.
move the pivot from about 3.5 to about 4 inches so that the levers will have less throw
have some adjustment in lever to allow fine tuning.
try to fill the hole in the floor better so less air would come in the cab.
upgrade the look so it looked less hacked together.
First was to replace the tcase end links with rod ends

I then made a mount for the a 3/8 rod end to mount to the d300 shift rail

I will skip to the end on this part. I used the shoulder of a 3/8 bolt to make a pin to fit into the end of the rod end, this pin will slide up and down as the lever moves in an arch, this will reduce the binding and any up/down pulling on the d300 shift rail

As for the hole in the floor I have always used a piece of foam. This works pretty well. I added two pieces of rubber on top of the foam.

So on my old levers I welded a 2 inch long piece of 1 inch steel onto the end of the lever. This worked well but was not removable, so to remove the console I had to un-bolt several pieces from under the jeep to get the levers off. After dropping my belly skid plate. So I started trading some emails with my machinist friend in Durango. I wanted to drill a 1/4 hole through the center of a 2 inch long piece of steel. Of course as you start to over think this, there is plenty of ways to screw that up even with a drill press. The two critical things are making sure that the steel is cut at exactly 90 and drilling in the center of a round piece of steel. He of course said it would be easy for him, so I asked him to do it for me. He looked through his scrap and didn't have any mild steel, he only had stainless steel.
(these are so bling-ing I am going to put them on the next post)
Wait for it
