Re: 1949 GMC panel truck...what company makes ladder bars or caltracs ?

Probably the simplest way on that rig would have been to keep the stock swivel mounts that held the torque tube rear axle in place and build a torque arm that ran from the rear axle to a pivot point next to the U joint that is somewhat similar to what was on 82/02 Camaros and Firebirds in function.

The Caltrac or that Tuff country style might work but no one makes anything specifically for the application and you have to build your own or find someone who can build it. That setup is designed for spring over axle so to work as designed you have to come up with an axle bracket that mounts under the spring and circles the axle to mount the top pivot inside the frame rails. Then your front pivot has to be mounted in the proper spot by the front spring bolt.

There isn't going to be any free lunch on this one.
