Every time I drive my car and then let it sit overnight the the coolant in the overflow bottle goes down a little bit. There are no obvious leaks that I can see. Thinking about the sources of the leak:   1. Coolant is leaking into the pistons. Not likely because the block was decked and the car has a new head from EMS. The oil is not milky and is not rising. I torqued the head bolts to 72 pounds. Searching I see Indiana say to torque to 120. I never retorqued them after a heat cycle.   2

Does anyone have a non AC blower duct for sale?

There are 2 plastic caps with nipples.Need one towards front of vehicle. Not sure if they are the same. Thanx!

Where do I start? Where can I get a new switch cluster?
