This was obvious on my 69 but I haven't pulled up the floor mat yet to have a look see.
I'm in the process of doing a cab swap on my '86 4WD. I am using a '79 2WD cab due to it being completely rust free and readily available.

I was contemplating cutting the hump out of my '86 and welding into the '79 to get the higher hump. But I have been told that there should be enough clearance for the bell housing. I think the high humps were designed to raise the shifters up closer to the driver. Whether it was the manual shift or a transfer shifter.

So as for converting your automatic to manuall....the only think that I know of is that your shifter will set a couple inces lower and may not be as comfortable to shift. Could get a longer shift stick, but that would create a longer throw. All personal preference that I can see. But should all fit.
