Most are gone now, so 19.5’s are the next best. They only come on GMC 3000 and 3500HD trucks, not hanging on trees. Start looking now.
If you want to make your truck original and keep the 20’s, Coker makes 20’s. If you want to make your truck a highway cruiser with larger engine, you will need to find modern axles.
GM ff 14 bolt rear axles are an economical alternative, any GM front axle, either IFS or solid will bring you disc brakes. Watch axle width. Both these axles are 8 lug which are not original bolt pattern. If you want 10 on 7.25” bolt pattern, have to do some more work. Let us know when you get to that point.
Reading on modern disc brake axles at top of forum in locked(2) topics to keep you reading when weather is bad.
