Panhard Bar Material

[SCOTI]

So my 'project' lately has been building a 4-bar/bagged set-up for my 89 square body CC dually using an older/used 'Ride Tech HD bolt-in kit' as my starting point.

The Ride Tech kit was not designed to be 'used' @ my planned ride height (my ride height = lower than their air'd out height) so several changes were required for optimizing my set-up. So far I've changed the 4-bar ends, fabbed my own front 4-bar mounting brackets, tweaked the bolt-on rear end brackets, installed step notches (Thanks PB!), & built new shock mounts to work w/the other changes.

The last thing I need to fab is the Panhard bar set-up. The Ride Tech kits utilize a set-up that is secured to the rear end w/the differential cover bolts & positions the bar slightly above the rear end. This works well @ their expected height range. The bars placement doesn't work well for my set-up. Their Panhard bar kit is also intended to to be secured to the frame w/a bracket that bolts to the inside of the frame rail. Since my frame rail is now boxed, it changes the placement of the bar which makes their differential bracket an unlikely choice.

I only got the bar minus brackets when I picked up this used kit so I've been trying to work w/what I had. I got a bracket for the 'frame' end of the bar that works w/the PB step notches & was going to build a tower that attaches to the rear end axle tube to locate the other end of the bar.

The problem now is the bar that I got w/my used kit will now be too short. I've searched the net & cant seem to find the same size tubing in a longer length (1 1/8" OD x .219 wall DOM). Ride Techs universal bars offer no size info & to be honest their 'new' stuff is typically out of my budget.

Where's a good source (other than Thorbeck Bros) for this material?
