I had the Enderle kit on my sheet metal tunnel ram with 2 x 850's. I liked the kit. Easily adjusted. I had 1" spacers under my carbs so I bought a piece of aluminum hex stock, drilled and tapped it, for the rod from the intake bellcrank to the crossbar. I installed the crossbar mounts at the carb studs, but I've seen pics of them bolted to the top plate hardware.
