Different width torsion bars on a SA gearbox????

[ed]

Did type3 swing axle cars come with long or short torsion bars????

My spring plates have a long tube on them, but I have seen short tubes and have been sold some aftermarket spring plates that are 2" lowered already with short tubes like a beetle?

I'm very confused

On the KCW website he is working on a swing axle type 3 with short torsion bars and short tube spring plates....
