broken torsion bar? what to replace with and how fun is it to do?

are your bars clocked or the same hex at both ends? PST bars over 1.00 IIRC have been made with early non clocked hex (same, bar will sit flat at both ends) and later clocked (more like OEM) When I worked with mine, I used a large pipe wrench on the LCA socket and used my foot to push it CW (unloading) and the bar slid right in. If you do get a nick in the bar, you are supposed to dress it down with a file or replace. I heard a van break a torsion bar when I was waiting to cross a street, sounded like a gunshot. I ducked instinctively and then noticed the vans front tire on the stops.
