QA1 Tubular K Member - Who runs one on a street car? Reviews?

I put one on my 70 Duster. The installation of the K went great and it gave lots more room underneath. I replaced the LCA's with QA1's at the same time and got PST adjustable strut rods. Biggest gripe was the strut mount on the driver side was likely not welded correctly. When the strut bar was in the LCA, the swivel mount would not line up with the hole in the K member. QA1 thought it was a bad LCA, so they sent another. Same issue. They said their K member could not do that, but they would investigate and let me know. Never heard from them again. Ended up heating & bending the strut rod a little to make it fit. Very frustrating to spend that much money on those parts to have that happen.
