I purchased a 1970 Chevelle last year with a 4 speed Trans( on the floor), bench seats( no console). The car originally had a automatic trans on the column. Here's the question; I replaced the old 4 speed shifter(Hurst) with a new Hurst Competition Plus shifter made for a 70 Chevelle. The shifter boot that was in place was a Hurst Boot. With the new shifter in it appears that the Hurst boot does not fit properly,the shifhter is centered in the console but the bood plate is too far left. I even tried an original GM Shifter boot plate and boot but still no go, the hump will not support the plate bracket. Is the transmission tunnel plate (hump| different for an Auto trans than a 4 speed trans, since this may be the problem. Year One has a Hurst Boot available but I fear that this will not be the answer if the tunnel is wrong. I really do no want to replace the tunnel plate. Has anyone had a simialr experience with good results. I do realize that I may have to replace the front carpet. As much as I would like to have the GM factory bootlook any boot will do as long as it looks and fits propoerly, Thanks

Yes, the floor hump should be differnt for a manual than an automatic. At least it is for my '69. I have converted mine to a manual and I am going to have to weld in a new hump plate to get my console to mount properly. Hopefully someone who is a '70 expert will help you more.

Ditto to the above. Also there are two types of trans humps for 4 speed cars. There is the console version and the none console version. The console version is more rectangular shaped and designed for the boot that is used with the console. The other is more of a square shape. This is the one you want if your not going to install a console.

Had to do the same on my car. The backyard engineers just cut a gaping hole in the side of the trans hump....I guess it could have doubled for a foot brake

Thanks, I guess the correct way to fix this problem is with a new tunnel plate installed, its got to look better then a big oversized boot. Can the new tunnel be pop riveted or must it be spot welded. Does the trans have to be removed for this task? Easiest and cleanest way to remove old tunnel? ANy other helpful hints?
