Center hump

To our knowledge there isn't, but I also can't 100% verify that cuz we haven't torn down a manual 2wd later truck

From looking closer to the picture of the 87 4wd /auto there looks to be an indentation where a 4spd shifter would sit so I would agree that they are the same. Parted out a 85 2wd/4spd a few months ago but deleted all the pictures after I sold the cab.

Unfortunately I did not take any pictures of mine of just the bare floor.

'87 2wd with MY6.

Bingo, looked thru some old posts on Facebook and found some pictures of the 85 4 spd truck I had.

Maybe some folks with very late production 2wd trucks (like '90-'91 crew cabs and Suburbans) can verify, but I seem to recall noticing a few trucks that were 2wd auto and had the tall 4x4 style hump. It may have just been '91, with 4L80e, I don't recall.

Couple of pics of 73-80 and 81-87 4X4 AT humps together.

@TotalyHucked that is probably the best floor hump info and pictorial that I've ever seen!

Took me quite a while of researching and amassing pictures to figure it out for myself!

am I confused my 79 1/2 ton has a high hump I am swaping out the sm465 for a m20 car trans
it looks like my hump is a high hump.
I think that would put lots of my stick (Hurst) ununder the floor pan level.
I am thinking I need a low hump like on the three speed trucks.
I cant seem to find one.
Anyone know if the high hump will work with the taller competion plus shifter.
Or where I can find a bolt on low hump for my truck
