Is your shifter located at the same place as my 1990 here?

 

My transfer case shifter is where your transmission shifter is, and my transmission shifter is on the column.

 

Ok, you got the other older style transfer case. Can't remember the model.

Don't know if it's gonna fit. I know there were the T19 4 speed standard with the 4x4 shifter right behind the 4 speed shifter. But never seen it with a 5 speed.

Your 4x4 shifter is like this.

 

It's in that spot, but it curves down and lays flat on the floor.
