Slant 6 on a V8 K Member?

Have a customer vehicle here in the shop who's K member has multiple cracks in various welds and torsion bar sleeves. He brought me a QA1 K member but it's the V8 style. I've tried multiple sources for conversion mounts but, as we all know, nobody goes from an 8 to a 6.

Anybody got insight? Save the day? Be the hero?

Thanks for your time all. Much appreciated.
