front suspension

I have heard of using the transverse torsion suspension to update the 40s-50s cars.
I believe their is at least two different widths to choose from.
Every car I have seen this suspension used in required cutting and welding to the original frame to get the suspension to bolt in.
They are a good option but not an easy bolt in swap to a early A-body or any body they didn't come factory in.
Similar concept as the mustang II conversions but much sturdier.
