Well no offense to you, but you also have spacers between the frame rails and K member. That is something that I would never do. The tapered shank of the K member bolts were designed to positively center the K member to the car structure. Given that you did this, I also suspect that you may have installed the transmission lower than others might. This would result in less transmission tunnel mods.
I'll ask again, have you done one ? I thought you were smart, NEVER SAY NEVER , LMBO. NO my trans is not lower than others, if anything it is higher.
this picture is before I shimmed the K frame
