Weber are common:

This is for the Weber 32/36 DGV. This setting has worked very well for me and will at least get anyone else very close to a good setting:

Idle Jets 55/50
Main Jets 175/170
Air Corr Jets 200/190

You can buy a kit from Kaiser/Willys with the Weber as well:

32/36 DGEV CONVERSION CARBURETOR KIT
FITS 53-71 CJ-3B, 5, 6, M38A1
Item # 923804
Print Product Info Email Product Info Share
32/36 DGEV Conversion Carburetor Kit

Replaces:
Carter YF
Carter YS

Application:
4-134 engines

These 2-Barrel carburetor kits can deliver more horsepower, fuel economy & dependability than stock units. The 32/36 DGEV conversions can deliver up to 18% hp increases over factory carburetors as well as up to 10-20% in fuel economy (depending on driving style).

Experience significant gains in torque & driveability and better acceleration without flat spots. These retro-fit carburetor conversion kits are designed to replace the sometimes problematic Carter or Rochester carburetors without replacing intake manifolds. Not legal for highway use in California.

Yes this looks a much more sensible option than stock stuff . What sort of fuel delivery pressure do we need here .......does it still use the standard mech.pump ?
