I purchased a second hand Mark IV Nova dash as the previous Mark II didn't really allow much space for the new heater / AC unit I needed to fit.
I fibreglassed in an air duct
channel to make it easier to add the air vents for demisting later
The new heater / AC unit fitted (but only plumbed in for the heater currently). The AC piping will have to be a job for next time.
The new quiet Hydra-pack hydraulic pump is fitted replacing the previous Smiths Mini Pack
(which worked well but was very noisy in operation)
