I was able to use 1350 shifter and linkage. The bottom of the shifter itself would hit the transmission housing preventing it from going into 2 wheel and 2 hi, so I had to trim about a 1/4" off the shifter base.
The yellow is what I had to trim off. I welded the lever on the backside since I ground so much off the edge where the lever is pressed in.
My next issue was the little arm on the tcase. The shifter was lined up with it rather than being offset, so I had to cut the arm and offset it.
I also threaded the stud, so I could put a nut on it incase it trys to flex and pop out
Its hard to see, but this is where the lever had to be trimmed to clear the tranny
I was able to cut my hole dead on the first time

I measured the where the handle was in relation to the bolt holes so I could mark out my hole. Then after I got the plate cut I used it as a pattern for the floor.
The lever is hardly inside the the console.
The hole is completely hidden.
Here what I started with
heres what I ended with, its offest about 2"
I cut the threaded prortion off off the stock shifter and welded it to a peice of 1/2" rod that I put 90* in.
I Had to trim the console out a good bit
The lever is almost touching flloor in 2 hi, but 4 lo it is 1" away.
I made it hug the console to keep it away from leg.
I spoke to soon when I said I cut the hole perfect on my first try. It turns out I didnt make it wide enough, so when I had everything back together and went for a test drive, I found out that when I give it a little gas the transmission torques a little and the lever rubbed the edge of the hole making a terrible scratching/popping noise. So I had to take everything apart again to trim it up a little bit.
I am still playing around with different boot ideas, I am using a piece of rubber that I cut slits in, but it doesnt flop down arounf the lever very well. I am looking for some sort of brush or boot from a car with a hand operated e-brake.
