[**grumpy**]

The rear of my 60 had jeep TJ springs. It lowered it 4" or so, and rode real nice. Only drawback was you lost some load capacity, but the only loads I ever carry are like what you see in the pics...my kids and friends, plus all my wifes vintage coolers and luggage...haha


As for the front, Im not exactly sure, but i did see it covered on this board, where guys pulled the torsion bars out and rotated them, sorta indexing them I guess.
Reminds me of what vw guys do to lower bugs.
Search all the torsion threads on this and the suspension boards here. Thats where I saw it.
