Scott I actually do use the heater a little. I never drive it with the top on so it can get a little cool in the evening along the coast. We pulled some more parts off today. We finished with the fuel system, the parts that are part of the USA emissions will not be going back on. We also pulled off the 2 piece engine bulkhead. One piece being aluminum and the other fiberglass. In my 74 they were both aluminum. We pulled the fiberglass trunk which also is 2 piece with insulation in between.
