During my reassembly of 2511 after repair of the collision damage and the repainting, I installed an aftermarket Restomod HVAC unit, Kenwood touchscreen and added HVAC vents at both outer sides of the dash
It took me hundreds of hours. Mounting the HVAC unit required designing brackets and modifying output vents to supply cabin, floor and defrost zones. The outboard vents required modification of the glove box support and the driver side steel dash structure. Ducting to the driver side vent is very restricted due to the steering column support.
I basically did what Denny’s prototype does.
At the point this article was written it appears there has yet to be an actual dash/console installation performed. I am quite sure they will find the same obstacles that I faced
Unlike you I would most definitely not want to be one of the first to attempt the DYI installation of a kit or to leave the car at Denny‘s for his shop to perform the installation.
whatever approach is taken one must consider the downtime required to perform the task. A DIY approach follows your own timetable, while a shop installation puts you at the mercy of their timetable.
I would most definitely wait to receive other owners’ feedback, from those that took the DIY approach and to those that elected to have his shop perform the upgrade.
