Scotty as to the mount that is showing that appears to be similar to the one I have on my car. The Bill Thomas mounts are four pieces. The two tower pieces that bolt to the frame in place of the stock towers (they are similar but not the same). I seem to remember that the BBC is a little longer and so it needs the towers in a different position. The other two pieces bolt to the block and fit kind of like a glove over the tower pieces with the thick rubber cushion in between. I believe I have an article on the mounts and installation but apparently my filing system is not as good as I thought. Will look for it if you want. I agree with your other changes that would help tidy it up. Overall pretty nice job though.
