Big or Little Hump
 

I've got a 92 D350 with an automatic that I'm trying to order carpet for. Is this the big or little transmission hump?

Thats the little hump

Is that a Reg Cab ? That's a Rare site to see .

Yep a regular cab. That's why I was up in the air about the big/little debate as it seems it could go either way.

Yup, Smaller aka "imperial" style hump.

Since there is such confusion on the big hump/little hump and ebay, would it be ok to just order a non-diesel 2wd auto carpet? Or are the gasser cabs different as well?

well I know a gasser cab (86 or 87 truck) with the little hump would hit my transmission when I put the cab on my 91 back in 2008. I had to cut the whole hump out and bolt the big hump in it's place.

From what I remember, that looks a bit bigger (and differently shaped) than the gasser hump I had. Whether that makes a difference or not for the carpet I have no idea.

The guy to ask is Mark Nixon. He knows about all there is to know for these trucks. Both gas and diesel.

That is exactly like my 90 standard cab automatic small hump. I replaced it with a big hump for my 4X4 conversion.

All 4wd trucks whether auto or manual, as well as 2wd manual trucks, have the large transmission tunnel.

The only small transmission tunnel would be a 2wd with an auto transmission.

That is what I've gathered in my years spent here.

That's also what I gathered from multiple sources. I had to swap my small one out for a big one to make my swap easier. The large one fit over the small one to draw the cut line no problem.
