In our 1972 4/4, the passenger side of the transmission tunnel gets very hot on a trip of more than a few miles. It has done all the time we’ve had the car (3 years). We are planning a trip down to Riom, with legs of up to 6 hours if we avoid motorways. I wondered whether I could install some insulation over the tunnel, but under the thinly padded cover or is cooking my passenger’s calf an essential part of heat dissipation?

Any ideas on what would be the best insulation to use, please?
