When installing the torsion bars, I know they are side specific (R and L), but does it matter for indexing which way they go in? Numbers in front or rear? These are the PST 1.03 bars and they are going into QA1 tubular lowers if that matters.
Also, I believe these bars are offset and it should be very obvious which way they go into the LCA. But should the adjuster bolt be backed all the way out or in enough to have the block putting slight pressure on the lever?

Im doing the whole front end and this is the first step. Im sure Ill have plenty of questions along the way. Thanks for the help!
 
It doesn’t matter which side is the front or back, but for future reference it helps to put any identifying stamps or castings to the rear. That way you can easily identify that the bars are in the correct location (L/R) or what size/brand they are.

The PST 1.03’s do have an offset now, they didn’t when they originally came out. Not all larger bars have an offset, and the ones that do are usually less than the factory offset.

With the QA1 LCA’s don’t follow the FSM description for clocking the LCA. If you let the QA1 LCA “hang down” it will hang straight down. The original LCA’s are wider and hit the K frame before they hang down that far. So, I would start with the LCA parallel to the ground, and then move it down to the first “flat” on the torsion bar hex you encounter. You should probably hit that flat before the LCA is hanging down more than 30* or so. You’ll want the torsion bar adjusting bolt backed all the way out but still in place in the adjusting plate, and keep the lever near the plate during install. Put some grease on the torsion bar hexes, but don’t pack the LCA anchor with grease.

What 72blu says^^^^^^^^^^^. the man knows his suspension chit.
One tip - you will need to have the shock absorbers disconnected from the LCA. Dont ask how I know. LOL
