It's also 5x114.3 if looking at the so called metric rims.
Depending on center bore and offset - Toyota, Honda, Ford, Chrysler are interchangeable.
With the right type of spacer, the world of rims goes wide open.
That stated, this may change suspension dynamics, but a 1.5" spacer with a 1.5" offset rim means 0" offset for suspension.

Problem with stock studs are that hey are about .500 too short for modern Aluminium wheels. They are only good for steel rims or long shank mag lug nuts.

You could change out the studs with 2000 Jeep, which are about 2.0 inch length, or 1.72 from end of knurl. Not sure which stud year and make but there Is a 2.2" stud as well.

PS, some metric wheels require factory metric lug nuts as they are wider and deeper at the bulge or shank that holds the wheel within the holes.

I found GM S10 1/2" lug nuts perfect for metric acorn style rims. They are beefy and accept 7/8" wrench.

Saved on-hand info about AMC Rim Wheel Center Hole / Bore & Hub Diameter...
There's Lug-Centric style rims and then there's Hub-Centric style rims...

>   AMC CTR Hub Hole Dia = 2.815/2.830 I.D measured 1969 stock steel magnums
> Moser CTR Hub Axle Dia = 2.815 O.D measured on replacement 1-piece Moser Axles
>  Ford CTR Hub Hole Dia = 2.785 O.D. per a forum post ????

  304-dude,  I respectfully have to say that this info you have given is incorrect.  The stock studs are not to short for current aftermarket wheels and i have had no issues while using the correct bulge lug nuts with the studs being too short on my AMX.  The only time that you will start having the issues as you claim is when you use or require a spacer between the wheel and the rotor or drum assembly and then you will have issues that may require longer studs. Aftermarket wheels companies are not going to build a wheel that the center assembly is too thick that it fits only one car and or that will require modifications too fit another. They have engineers smarter than that.

OK, just stating not all wheels have the same thickness between bulge seat and hub flange.

I should have stated that, in stead of making a flat out remark. Though my comment was on the option for other make wheels, as my experience with aluminum wheels have been one sided on late / modern oem spec wheels.

Perhaps wheels made to fit AMC will be just fine across the board.

Should correct my post; don't use spacers ever. In fact they are not legal in some jurisdictions.
5x4-1/2" x 5x4-1/2" bolt on adapters (also called spacers) is what I have used. No long studs or modification to factory axle.
More money but way safer.
