Torsion bar direction

It doesn’t matter which end is forward. If both ends aren’t stamped with the ID number I put that end in the back, so you can see what’s in there later if you forget or someone else gets the car. But as long as the left side bar is on the left side and the right side bar is on the right it’ll be fine.

I also have the torsion bars identified as USC 891L and USC 890R on my 71' Demon. I recently rebuilt the front suspension and converted to front disk brakes. I also pondered the front/rear orientation of the torsion bars because, IF the rotation of the bar is important, the way you put the left (or right) bar in will reverse the rotation. I had cleaned up and painted the bars and fortunately I left a witness mark on the left bar that had sassy green overspray on the USC 891L end. I figured that the only way to get overspray on that end is it had to be in the rear position. In summary:
USC 891L marking Left rear by clip
USC 890R marking Right rear by clip

This is all assuming that seeing I just got the car last summer, that no one had messed with these bars in the last 50+ years and they were in there from the factory install.
