Another anti-rollbar question

Has anyone on here made or fabricated a solid anti-rollbar for a fox or it have to be adjustable?
Thanks

I would want it adjustable. Of course I use it to tune the suspension if needed.

Made my own for the Pinto. Used 1" CRMoly tube x .100"(?) wall. Used 1" x 2" rectangular tube for the arms, carved as needed. TIG welded to the tube (be sure to use the right filler rod), in the appropriate location. Made some bearing housings outta spare materials, and bored to fit the tube. Used 1/2" rod ends to make up the adjustable parts to attach to the rearend. Needta use split collars to hold the assembly in the bearings. It works real good, and the price was right.
