torsion bar re install, too high too low

Reinstalling torsion bars on a 71 scamp(first time for me). They end up with way too much tension with the car a good 6" above ride height or bottoming out with no tension at all. Right now I have the lca and spindle supported with a jack to get the uca on, but its pretty much lifting the car off the jack stand. Seems like I am missing something. Any suggestions would be appreciated. Thanks!
