Haven't checked yet. I spent monday rebuilding the bolldy %$$%#ing quadra jet carb, by the light of my truck headlight, and haven't had time to work on the truck since then. I've got to put my outer duals back on, and reassemble the boom (had to get light wieght - 5760, much better than the 6300 prior - $50 less to dmv.

) before I worry too much about windshield wipers.
Anyone got any info on the heater question?
