That's funny Andy, I bought one of the 120 Amp kits and put it in my B engine'd A body. It fits, but it's tight in there- but everything's tight in a Big Block A body. Not a great picture, but the best one I have right now. The output stud is close to the RPM head and the plastic piece on the stud had to be removed. I replaced your supplied hardware with the buttonhead allen bolts, soon to be replaced with ARP stainless 12 pnt hardware.
