The Dana 20 transfer case has a 2.46:1 low gear ratio. In early 1973, Ford switch to a 2.34:1 low gear ratio. These transfer cases used two different shifter designs known as either the "J" pattern or "T" handle. The "T" handle was used from 1966 to 1972, and the "J" pattern from 1973 to 1977.

We have two New stock type shifters T-shifter (66-72) w/Boot  and J-shift (73-77) w/Boot.
Just unbolt your old shifter and install our new one. It mounts in the same place as original. Oilite bushings give smooth trouble-free shifting. Comes with boot and mounting hardware.

 

Dana 20 Twin Stick Shifters We get calls all the time about the Dana 20 being "hard to shift". After shifting hundreds of these T cases ourselves we would say it can take some finesse to shift the Dana 20. You can make it easier with the installation of a twin stick shifter. The twin sticks allow for shifting one rail at a time (front or rear) whereas the original shifters have both rails connected together, making it harder to shift. The twin sticks come with WH shifter knobs and mounting hardware.
 

The original twin stick for the J-shift transfer cases! Slight modification to shift rail and tunnel cover hole is necessary.

The Gear Gawker clear cover for the D20, this is a great way to keep an eye on your D20 not just the fluid level but if you look close you can see if their are any metallic partials in the oil indicating a problem without taking the cover off, This is an easy way to check your D20 before you go to an event. But are they strong? These are made of 1/2 inch thick polycarbonate glass made for the view slits of armored vehicles. These covers will take a serious beating and hold up to temps over 600* without failing.

This little part bolts on to the cross member and bumps up against the Dana 20. Made from polyurethane it is a little wider than stock in some cases you may need to re-drill the mounting hole to a 3/8.

You can now replace the old rubber mounts with these new mounts made from polyurethane they come in come in blue or black.
