Are suspension parts differernt for a V-8 K frame and the slant 6 K frame?

Good reading guys!

I called a shop for pricing. They quoted me $900.00.
That's $1600.00 for parts and labor.

I just may attempt this myself.

Any advice?

It seems PST has 10% off for forum members. Maybe I will go that route after all?
They have the 1.03 torsion bar you were warning me about though. Maybe I should call them first and address those concerns.
