Keep hearing about frame twist with 440s

The person who did the floor just took sheet metal and banged it into shape, instead of buying an actual pan. It's solid just ugly as hell. I need to see if it's actually in there correctly to weld the connectors to.
Shucks, 2x3” box tube up through the floor would tie that in nice and for damn near nothing. If I didn’t put a new full floor pan in I would have ran them up and through the floor. The USCT fit my AMD pan with very little modification. The picture I am posting is from Mopardude318’s post about 10yrs ago. But it shows the slice and thru method.
