Sub-frame connectors... Please build them correctly!

I remember seeing that vid of torsional stressing.
Only thing I could find:

US CAR TOOL 1970-1974 Mopar E-Body Cuda/Challenger Uni-Body Rigidity Test - YouTube

pretty interesting.....

like to see the same test WITH the K ....and doors in place.

wonder how much weight that 50lb crankshaft LEVERED out front like that is simulating?
