[44th Miss Inf]

Ok, hopefully this will be clear as mud

First two pictures are of an 84 up 4wd 4 speed hump at firewall and near/under the seat

3rd picture is the 81-83 4wd 4speed hump (this one has the section around the transmission hole cut off center, and turned around placing the hole rearward 3” for an NV4500 swap, retaining original shift boot etc) on an 87 low hump tunnel. Looking thru the t case shifter hole, you can see where it doesn’t conform to the floor, leaving a gap, but this is easily massaged to work.

The last picture shows the gap at the back of the bolt in hump (about 1.5 inches) that you will either have to raise the t case hump to match, or install the rear hump piece from the cab you got the hump from.

I did not get home in time to go to my other place, as I have an 86 2wd 4 speed truck I can compare the hump to the 4wd one, as I believe the 73-80 2wd and 4wd humps are different. I only own 81-up trucks now.
