Good morning from the USA!
I am purchasing a 1991 Japanese 2.8 turbo diesel MU, and I have a few questions. (Yes, I've searched the forums for this information, but I've been unsuccessful.)
Here are a few picutures of the truck:

In order to determine the gears I currently have, I'm assuming I need to open the differentials. Here are pictures of them:

First, I read the head gaskets often blow on the gas engines and that OEM replacements are highly recommended since the aftermarket ones don't last long. Where can I find OEM differential gasket seals?
Also, what is the top speed of a stock 2.8 turbo diesel?
Where can I order a gear to calibrate the speedometer?
I may need to regear the vehicle. It has 285/75 R16 tires installed. I also heard Japanese vehicles are geared for Japanese roads, where the max speed limit is 60 mph or so. With a 2.8 turbo diesel engine, a Japanese drivetrain, 32.8 inch tires, and 80 mph speed limits in my state, I'm sure I need to change my gearing. Does anyone have any suggestions on gear ratios? Once I determine the ratio needed, where can I purchase the gears?
Speaking of the rear differential, my father purchased at least one locker for his first gen trooper. (I'm 80% sure his Trooper was a 1989 model; it was definitely after 1987.) I can't remember if he bought a front locker and/or a rear locker. (I think these are the pneumatic ARB units.) Unfortunately, he passed away, so I can no longer ask him. Thankfully, I think the parts are still in storage. Will the front and rear lockers from a Trooper work in a MU?
Since the vehicle has oversized tires, it has a "mushy" feel when driving. The steering isn't super-responsive and the vehicle doesn't feel the most stable at highway speeds. Are there any stabilization kits that can be purchased to mitigate these symptoms?
Furthermore, I'd like to purchase a front winch bumper, a rear bumper, and rock sliders. Does anyone else produce such items besides Calmini? (Recent reviews of Calmini have caused me to question whether or not I should do business with them.)
Thanks!
Bill
