I'm having trouble understanding what you're describing. Are you saying that the distributor rotor shaft is not spinning? Or are you saying that one of the ears of the distributor shaft made contact with the pole piece of a pick up coil (not likely). The distributor rotor is driven by the...

I would examine the slip yokes of both driveshafts. There should be ZERO rotational play between the halves. What you're describing is exactly what happens when the rear driveshaft slip yoke has play. When coasting, the 2 halves will "flog" around and cause a vibration.

Starter logic (small push-on connector)

The starter logic circuit is pretty simple: Starter logic (small push-on connector): Battery positive/FL AM1/fuse AM1/ignition switch/NSS/starter solenoid. Starter power (terminal lug): direct connection to battery positive. Starter ground is through the case that is bolted to the bellhousing...

Please don't compare specialized tires to road tires. That's apples to oranges. Not many road vehicles run drag tires, and not many dragsters run steel belted radials. Completely different manufacturing processes for completely different applications. We're specifically discussing road tires.

You're thinking about it the wrong way. There is a series of steel belts in the tread area that prevent the tread from expanding or contracting, while remaining flexible. The distance from the hub to the ground is not relevant because the tread is not changing length. It is simply flattening out...

Like I said, tires are not balloons. The tread length is fixed due to the construction of the tire. Think of a tire tread like a tank track or bulldozer track. It can deform and take on different shapes, but the length remains constant. The only time tire pressure would effect rolling length is...

Tires are not balloons. The rolling distance of a tire between 36 psi and 22 psi is unchanged. The contact patch is larger on the low tire and will cause higher rolling resistance, but that's it. Quite frankly, even if you put 2 slightly different size tires on an axle it wouldn't hurt...

Fwiw, the part number I listed (16400-66040) was for the OBD1 FZJ80. It is a direct fit for all USDM FZJ80s, and is what I have in my LX450.

80 Series OEM radiators (TRAD) have always had plastic tanks. 1991-1997.

Considering that the OEM radiator lasted 33 years, I would opt for OEM 16400-66040. Don't forget new mounting hardware and cushions regardless of which radiator you choose. As you'd be pulling everything apart anyway, a new OEM fan clutch, water pump, thermostat, belts, and hoses would be on my...

That's quite different from what you originally stated. I would fill the radiator to the top of the filler neck and use a pressure tester. It should hold at least 13 PSI (cap relief pressure) for a few hours without decreasing. That's the easiest way to identify an external leak. Any of the ones...

I find it difficult to believe that you're loosing 3 gallons of coolant after a few drives. If that were the case, it would be pretty easy to identify as it would be pouring out of the truck.
