I deleted my AIR system and bypassed the heater core diverter valve today.
Summit sells a dress up kit for our cars. comes with center bolt valve covers, chrome oil cap, chrome breather, chrome steering fluid cap, and a chrome brake fluid cap. I'm gonna scoop that set up soon

If you will notice I have moved the coolant bottle to the drivers side and removed the washer bottle. Other than that, the diverter valve is in the way a bit. But it works out ok.
