Trans tunnel removal

[kmanrsss]

Im going to swap a 2wd cab for a4wd cab and was curious how much stability is lost by cutting out the tranny hump? Should I have the cab almost in place before removing the hump, or will it still be sturdy enough to cut it on the trailer where it sits and moving it into the garage? I can't imagine it is a huge difference but others know better. Thanks

You will be all set just cutting the hump out.

Thanks. I didnt think you'd loose too much structural rigidity but you never know till its too late.

You don't need to cut the whole tunnel out, just the part where the 4x4 removable pan goes and the rear portion where the t-case goes.

Isn't that the whole thing.

When I converted a 2wd cab to 4wd. I had the cab sitting on a dolly that I made it was sitting on the factory mounting locations. I cut the rear tunnel out and when I welded the 4x4 tunnel in I used a jack and a 2x4 to support the floor when I was plug welding it back in place. Basicaly just to support my weight while welding.

I guess what I was trying to say was at the front from the firewall to the front of the seat hump, depending on your tunnel (most autos had a low tunnel) you just have to cut open the lip portion for the 4x4 piece to bolt back into.  Behind the seat hump you have to cut it out.

Kmanrss make sure you get the part that Capt mentioned for the transfer case clearance under the seat too.

My plan was to cut out along the factory seam in the tunnel, then get it onto the frame and see what else needed to be trimmed. The portion under the seat looks about the same height but i havent done an actual measurement, just the old thumb and pinkey measure. thanks for the tips.
