Why do C3 headlights droop? Ever see a C3 Corvette with droopy lights? Or see that the area around the headlights is all chipped up? Wonder why this happens? The horizontal bar that supports the headlights is made of lightweight metals. Over time these metals corrode, which in turn allows the bar to become detached from the fiberglass. As the bar separates it lowers the rear of the headlights, causing them to look bad. There are two different things you can do to remedy this condition.
1.You can try to adjust the headlights up. By taking a rat tail file and elongating the adjustment holes in the headlight bucket mounts and using an allen head fastener, you can get another half an inch of adjustment out of your existing setup.
	2. I f the light door cannot be adjusted up high enough you are going to have to replace the horizontal support bar. This is a labor-intensive procedure as the headlights need to me removed and the old bar removed before the new one can be bonded in. Dynamic Corvettes stocks all the parts and supplies required to properly repair your C3 headlights, give us a call for more information.
Corvettes don't rust..right? Even though the body of a Corvette is made of fiberglass there are still some components that are subject to corrosion. 1976-1982 C3 Corvettes feature sheet metal flooring in the footwells of the car. If the Corvette has had a leaky t-top or has been driven in salty conditions it's possible that these sections have rotted out and will need to be replaced. Speaking of leaky t-tops, the windshield frame is a candidate for corrosion if the chrome trim has not been properly sealed. Most of the time this problem does not become evident until the windshield needs to be replaced. When looking at a Corvette if you check around the a-pillars you can usually see evidence of corrosion coming from around the trim panel. Dynamic Corvettes stocks new sheet metal components for the replacement of the windshield frame. If this repair is not done properly, your Corvette could crack its windshield just by going over a bump in the road.	Corvettes are built on a full frame. These frame are very tough, but on a 30 year old car they may be corroded. The channels that run underneath the door fill with sediment, rodent nests and other debris. This debris packs toward the rear of the frame rail with corrodes the section where the wheel arch meets the lower channel. Replacement frame sections are available and we do keep a few rolling chassis around. Please note that replacing a frame on one of these cars is an expensive operation. You can help to extend the life of your Corvette frame by rinsing any debris out of the frame channel. This will prevent moisture from being concentrated in that rear area and subsequently rusting that frame section out.
C4 Corvette A/C airflow problem After a number of years of use you may find that the air conditioning performance of your C4 Corvette is lacking. There is a simple cleaning procedure that may restore the performance of the system. First remove the blower motor from the vehicle. You should then be able to see the evaporator core inside the blower motor housing.	Take a bright flashlight and look inside the blower housing, if your evaporator core looks like this this : Its pretty easy to see why you are not getting any air into the passenger compartment of your Corvette. Remove the resistor on the top right of the case. Take a garden hose and some light detergent such as Simple Green and hose out the evaporator core. Take care not to get to much water into the A/C system. Make sure that the water is draining out of the drain spout. Take a blow gun with a long end and blow out the area where the resistor mounts. Once the unit is clean of debris reinstall the blower motor, the resistor and run the system for a few minutes to completely dry it out..
