Still not feeling it. So the factory just cut the floor up to put the hump in? The link only had speculations based on swaps, seems odd that the floor pan would not have been stamped special for manual car. It also seems off that the crossmember would not have been special to follow the hump contours.
Update
I just went through the 67 parts catalog...1 floor pan for all, 1 crossmember for all.
I'm dumbfounded!
There is a part number for an auto and for a manual console pan but I could not find a photo reference so I don't know if it is the hump or something else.
