I've attempted to install a 4L60E in my 1937 Chevrolet 4 door. I have a transmission crossmember installed from Chassis Engineering, which is for a 700R4 but from what I've learned a 700R and a 4L60E should mount up the same. I bought a mount from a local parts house. I some bolts in but they won't tighten up. Am I supposed to put nuts behind these bolts? The reason I ask is there is so little room inside the mount it doesn't appear there would be room, but I could be wrong. Has anyone used this mount? It's the mount that has bolts that mount into it rather than a single stud sticking out.
In this first picture you can see the bolts sticking up through the bottom of the mount.
