1973 Duster 340 Torsion Bars - recommendations

So I need to replace my torsion bars. What are the stock degrees? do I need 20 Degrees, 15 degrees, etc... Right now the front end sits way too low, so I want to get some bars that I only have to adjust the LCA a little bit. Right now it is in all the way and sitting way too low. Any recommendations? Car has POL upper Control arms with stock lowers and all new bushings, end links, etc..

Thanks,

Scott
