Speedtech's Torque arm suspension question?

[chavie77]

Hello,

Has anyone installed and tested Speedtech's Torque arm suspension. I have a 68 firebird and I am seriously considering either the torque arm or 4 link suspension. Does anyone know if speedtech's #TARS12KIT 12 Bolt Complete and Assembled comes complete with differential, thirdmember, and axles with housing. If anyone has actually installed this unit, was it easy to install, is there alot of welding required, and how does it handle? What size tires can you use? Is a torque are suspension better that 4-link?
