Years for Removable trans hump
What year did GM stop the removable transmission tunnel on 2wd's and 4x4's?

Re: Years for Removable trans hump
That is good to know, I know that my 85 C30 3+3 did not. It was a solid floor like a burban.
although my 89 blazer had a hump that was glued in

Re: Years for Removable trans hump
i do not think any 2WDs have them unless they have a compound 4 speed. i have owned a dozen 1 tons with 4 speeds up through 89 or 90 and they all had them (makes a clutch or tranny swap lots easier BTW).

Re: Years for Removable trans hump
There was a point in which they stopped making the removable hump, I cant remember which year it was specifically but in 77 or 78 GM went through and did a major lightening to the bodies going to thinner metal, and they also redesigned some components, I know on the suburban and crew cab when they did this it lightened them by about 400 lbs.
I am not sure if this was when they stopped with the removable floor hump, or if it was in 81 when they did the next major redesign.

Re: Years for Removable trans hump
I can verify what others have said. I have an 83' k10 cab and the transmission tunnel was bolted in. My buddy has an 85 k30 and it's not bolted in.

Re: Years for Removable trans hump
Now that I am thinking about it, I think that the Crew Cab and the Burban share the same stamping for the floor. I bet that on regular cabs and blazers they kept the hole, just started gluing them in place.
