The bigger trucks have a different cover for the e-brake lever I believe. The cover on my 48 was rotten when I got it so I built a new one. There is a raised section that goes over the top of the trans that extends to the lever. It just so happens to be the same exact size as a 9" x 13" (I think) cake pan that I welded upside-down onto the trans cover in the humps original location. If you didn't know what I used, you would never know,
