Depending on where you want to mount your inside lift handle will determine how far you thread the tee fitting up on the threaded rod. The tee fitting is made out of two 1/4X20 1" long nuts (you can get this at the local bolt place). Weld one up to the face of the other to form a tee (see sketch 3 "A". Add 1/4X20 threaded rod to length and put knob on the end.

One you have a location for the threaded rod, drill a hole in the cab corner, large enough for your pipe, and weld to cab. Insert threaded rod thru the pipe, and cut to length, and add the knob (see sketch 3 "B").
