Yep, BMW dash goes completely except for the very front of it, under the windscreen, that has the de-mist vents in it. The centre console goes completely as well, and is replaced with a new, smooth, leather covered affair.
Heater controls are activated by pull controls under the dash...along with the fan and temp controls.....there are no "eye balls"....so heat (or cool) is just delivered up to the screen, or down on your feet...or both at once.
The "computer" is removed as is the fag lighter, front and rear fogs will be operated by period switching, four way flasher goes under dash along with an electric boot release. Steering wheel lock is removed and ignition switch moved to the central gauge console in the middle of the dash and a new 3d printed cowl fits behind the steering wheel. Then new carpets and new seats.
Sounds easy if you say it quick!
