FSJX2,
Here is Youtube vid of an example, it is a fair, not great explanation.
One very important thing I did not see is the proper way to attach cable to this new brace he MFG.
As there is No brace for it unless this example intends to do like the Hi/Low engage side setup use and heavy floor shift mechanism.

It title is “The original quadratic! why it kinda sucks and its kinda cool"
IMO it leaves some parts out and I would love to see someone redo this video and certain tasks disassemble / reassemble, and show things with perhaps a dimension of the plate & added bracketing that is needed to use a cable.
Though anyone can do the measure and figure out proper pivot measurements and types of connections to make it work.
Yes use oil remove solvent and so the rubber use gasket with "thin coat" of ATV, use both will seal better.
Shouldn’t need to disassemble unit once done now, for at least 150K Miles so don’t concern too much there about messiness.
Check the case mating surfaces for nicks and gouges, smooth out carefully, so no leak spots can develop.
Have a torque chart of all the bolts on hand.
I don’t have a website for repairs or even a YT video for my project, yet is a good idea for others to have so maybe someday will do one.
if I’m going to keep the truck and make it how I want it, the cable setup and 2X4 kit plus front hubs makes it rather more reliable then the OEM diaphragm type.
