I didn't take progress pics of the VA install on my '33, but the one thing that I would do different is to mount the unit about 2" to 3" lower than I did to facilitate easier routing of the flex air duct hoses. Mine work, but they're crammed in tight, with almost zero room to transition from vertical to horizontal, a PITB to install. I mounted mine high so that it would be out of sight on the passenger side. As for the penetrations on the firewall, the VA unit uses hoses between the unit and the bulkhead connectors, so you can mount the firewall connectors as you wish, provided you have means to route the hoses between the connections.
