'66 Barraduda front suspension won't adjust down one on side

All I can think of is to replace both torsion bars . It sounds like the left side twisted for some unknown reason. I say change them both so you don't have the same problem but opposite . the new one would be stronger than the old one. Do it right the first time so you don't do it twice. My grandfather always said it takes a lazy man to do it right the first time and an ambitioned man to do it over and over again. LOL
Thanks, but the problem has already been found. The adjuster arm and lower control arm are frozen together. The other side moves freely. I have sprayed it liberally with penetrant, hopefully they'll break loose in a couple of days. In not, I'll be applying some heat to it.
