Torsion Bars

[Rawls1]

Previous owner re indexed the torsion bars and adjusted the bolt. Any information on how to re spline them back to factory? I know how to remove and then adjust the bolt. I don’t see any marks or indicators to set the bars back to the factory marks? Any help is greatly appreciated!

1993 Isuzu pickup 2wd

Previous owner “ re index “ the torsion bars.

Is there any marks or indicators on the bars or lower control arms to put it back stock?

Thanks

there are no marks to indicate this factory settings.
The T-bars were installed at the factory by a machine with lasers to measure the correct height.

Trial and error to achieve factory ride height is the only wat to go about it.

Thanks for replying Idk what my issue is up front. I have pulled the torsion bars out and went counter clockwise on drivers side and clockwise on passenger side made a mark at 12 on the bar and went 360 trying to find the right spot. I’m keeping the rear key level and adjusting the bolt tight then loosing it 1.5 turn and truck is still not right. Idk where he started when he “ re indexed” then torsion bars Im stumped
