I KNOW this has been talked about before. (sorry)
I have looked (34 pages of threads when searching for "wheel") but I can NOT find the information needed.
I am looking to replace/upgrade the wheels on my 50 Commander.

From somewhere I have saved the following:
1971-76 all big GM cars
1977-90 RWD Cadillacs
1977-90 big GM cars with 11" rear drums
1991-96 all big GM cars
1971-02 5 lug GM G vans
1971-99 5 lug GM pickups
1985-02 2WD Astro/Safari
1973-79 big FoMoCo cars and some midsized models
Plus all big GM cars except for Chevrolet/Chevy based Pontiac from ca. 1950 to 1970
You should note that the '50 Commander wheels are the same as the 1/2 Ton Truck Wheels '49 to '64. -Stude Rich
What I am hoping for is someone to "endorse" one of the above options and/or to rule something out.

I know the 50 has the large brakes and larger hub and the need to have the recessed area to clear the brake.

Any help is greatly appreciated.
