Sealing a Shark: 1977-1982 Weatherstrip

Using aftermarket weatherstrip pieces in the past, we had to choose either adjusting the windows to seal, or adjusting the windows to roll up and down without the door open. There was no way to do both. ’77 and earlier models used a different style rear vertical weatherstrip that wasn’t solid so it made window adjusting only somewhat problematic. Front vertical weatherstrips are a problem on all years. The dense rubber just wouldn’t seal properly to let the window roll freely. Thankfully, newer offerings are as supple as the factory original pieces. (more…)

The radiator core support has two functions: radiator placement and front end support. Weakened core supports allow the nose of your Corvette to droop, increasing the gap between the upper part of front fender and the door. When that occurs, stress is placed on the inner fenders. Before the core support project begins, a thorough inspection of the attaching hardware and cushions is in order. We’re working with a rough but fairly original car, so we were careful to save the hardware and as many O.E. pieces as possible. (more…)

Corvette Central Exhaust Systems Overview, Part I

011 (Medium)

Exhaust systems have improved immensely from the early years when we would replace rear exhaust, mufflers and tail-pipes almost yearly on dual exhaust vehicles. Corvettes were no exception.  If they were driven infrequently with rich running engines, it destroyed the carbon steel exhaust tubing quickly. The rear of the exhaust system was most prone to damage as the moisture was blown backward and, in many cases, rarely dried up.  Most of us complained loudly when engine temperatures exceeded 180 degrees, saying that our engines would not last under the intense temperature pressure. That rise in temperature along with aluminized tubing just about put specialty exhaust shops out of business. Now we come to expect that an exhaust system will last the life of the vehicle, and in many cases, it will. (more…)
