So I just spent a couple of weeks of hell installing Vintage Air. An engine swap is soo much easier on the back and neck as well as faster than installing a new evaporator in a completed car.
Anyway my next install in my 67 was a single din GPS that now pops up and blocks the centre air vents
I installed 6x9s on the rear parcel shelf using plywood standoffs from Supercheap so no butchering required.
