Hey guys, trying to figure out battery tray location. The first pic I am posting has what I believe to be a 40 at a car show with the correct battery tray location. I set mine up there as you can see but came across a problem in the rear mounting hole. What am I doing wrong?? Looks to me like you got it right, but why is that battery box bolt tab "bent" in such an awkward manner? I tried to take photos of that particular tab and how it bolts to the frame but wasn't able to take the photo. I believe that particular tab is held in place and hidden by the same bolt that holds the inner fender panel. You can see the silver colored nut up inside my frame in the second photo that secures it.You may have the wrong tray as your bolt tab looks different than the one I bought in a Drake catalog from long ago in the 80's (shown)? Mine fit all 3 try bolt holes in the frame - 2 on top, 1 on the side. You could modify the tab without too much work.
