"... around 40 to 70" is a large range. With the engine at normal operating temperature, what does it read at idle? What does it read on the highway at 60 MPH in overdrive (around 2,000 RPM)? If you're sitting at idle, in neutral, and you blip the throttle -- does the oil pressure show a momentary jump, or does it sit still?

Try the super basic gauge test. Ignition on, but you don't need to start the engine. Remove the wire from the sender and isolate it. The needle should go to 80 (or peg to the right). Then ground the wire to the head or to a bare spot on the chassis. The needle should go to zero (or peg to the left). If it fails either or both of those tests, either you have a bad gauge or there's a problem with the wiring.

Correct.

You don't have to install the tach in the dashboard to test it. You know those two yellow connector blocks on the right side of the engine bay in the Renix years? One of those is a tachometer outlet -- and one is a ground. You can connect an idle tach to the engine, use jumpers to connect the tachometer you want to calibrate to the diagnostic port, and check it that way.

Thanks for the video. That basically confirms what I had read -- that there's a high probability of breaking something when installing the new units. Got my fingers crossed.

Yes, they do help.

Yes, that's correct. The Jeep wheels are "hub-centric." That means the center hole is sized to fit precisely around that raised center section of the hub, to help carry the weight of the vehicle. There are other vehicles using the 5x4.5 pattern wheels that aren't hub-centric. Ford Ranger/Explorer wheels, for example, use the same bolt pattern but don't have the same center hole diameter. Many aftermarket wheels have a larger center hole and aren't hub-centric. Back to your original post: What's your idea of "vintage"? Are you looking for something that, at one time, was OEM on a Comanche, or are you looking for something that looks like it came from the 1930s or 1950s?

But the Jeep 4.0L starts off with 6 quarts. When the parent engines were used in AMC cars, the capacity was only 5 quarts, and the engines routinely lasted 200,000 to 300,000 miles. On dinosaur oil.. Jeep uses a larger/deeper oil pan. How much additional oil do you need?

Has anyone replaced the headlights in a ZJ Grand Cherokee? Not the halogen bulb -- the entire lens/housing assembly. I need to replace both sides on a ZJ. I have the new units, but I've heard tales of breaking them while trying to install them. What's the inside story?

^^^ This. Step one is to verify which set of holes your cross member is mounted to. Step two is to confirm with Rusty whether or not you got the right length arms for that set of holes.

Fixed.

2.45 or higher rounds up to 2.5. 2.44 and lower rounds down to 2.4. I'll see if I can fix it.

Looks like they had several of them there. 13.6 second quarter mile, right off the showroom floor. (Yes, back in 1969 13.6 was fast.) My brother had one. What the photos don't show, because the hoods are raised, is the "mailbox" hood scoop. They had a large, squarish hood scoop mounted above the air cleaner can. IIRC, it had an inlet flapper that was held closed by engine vacuum. Opening the throttle lowered vacuum, which allowed the flapper to open and get more air through the carburetor. Thwey drove surprisingly well. I borrowed my brother's once, showed up at an autocross on cheap Kelly-Springfield street tires, and beat several Corvettes.

Nonetheless, the oil is bring pushed out because the crankcase is being pressurized. There's always some blowby but, in a healthy engine, the PCV system can handle it and suck the oil fumes through to be burning in combustion. If you have oil blowing out the fill cap, either the PCV system isn't working (which could be a clogged line or a bad PCV valve), or the piston rings are worn and there's too much blowby for the PCV system to handle. Can you run a compression check and post the numbers?

Those LED replacements look like what I need. In my garage, the 4-foot fluorescent work lights are basically useless in the winter, because it gets so cold they don't put out any light. Are the LEDs immune to that problem?

Don't forget AMC ...

What's your idea of "vintage"? To me, this looks like you're asking about the ten-spoke "turbine" wheels from the mid-80s XJs and MJs.

This thread is getting confusing. Let's let Omar clarify what he has, and what he needs. If you want to eliminate a/c from a vehicle that has it, just remove the compressor and install an idler pulley to maintain the belt routing.

Someone took it out? So the dash controls and the under-dashboard parts are there? That would make things a lot easier.

It's the jack handle. Cherokees used the same jack and handle, so just get one from a wrecked Cherokee.

Sorry for my contribution to thread drift, but I felt I had to correct misinformation. The problem with bolting to the rear of the cab is that you're punching holes in a vertical wall, and that invites water in. If I were going to bolt in a safe (which would be a small handgun box, for me), I'd bolt it to the floor, set some silicone sealant around the bolts as you install the safe, and then seal the crap out of it from underneath after it's in place.

Much closer to a needle in a haystack.

Before seeing this video, I didn't think I would ever want to buy a retreaded tire. Now I KNOW I never want to buy a retreaded tire.

Youtube video of Chinese automobile knockoffs -- and they didn't include the Cherokee.

Please provide the case citation, because I think you're wrong. The usual law cited for firearms in federal facilities is 18 U.S. Code § 930 - Possession of firearms and dangerous weapons in Federal facilities. But the Postal Service falls under a different law, 39 CFR 232.1. This says: It's the "official purposes" clause that allows postal patrons to bring an unloaded firearm into a post office for mailing. As noted, under other laws only an FFL can mail a handgun. It's illegal for anyone, even with a carry permit, to carry anywhere on USPS property or to leave a firearm in a vehicle if the vehicle is parked on USPS property. That's what the law says. If the Supreme Court has ruled that this is unconstitutional and can't be enforced -- give us the citation. I know a bunch of firearms attorneys, and none has ever mentioned that this law has been ruled unenforceable.
