what dia t bars should I buy? & what shocks should I get?

Go do a full coil spring conversion.

KIDDING!!

1.14 torsion bars, hotchkis shocks.

Chassis connectors and torque boxes help HEAPS!!

And a sway bar...definitely.

This is my setup exactly...I have to report that it rides hard and still doesn't feel that great. If I had to do it over again, I might go for a smaller torsion bar.
