According to the build sheet glued to the gas tank, this Stingray was delivered to a dealership in Jacksonville, FL in 1976.  I bought the car in December 2004 and have been working on its restoration ever since.  The early stages of the project can be found in Part 1.  Below, I describe some of the more recent work.

floor beforeWhile the fuel lines were out, I decided to replace the floor pans.  Over the years, the leaking T-top panels had allowed water to pool on the floor, and the floor pans rusted completely through in several places.  A previous owner tried to solve the problem by laying fiberglass across the whole floor.  While these patches allowed the car to be driven, the floor was very uneven and all the mounting points for the seats and seatbelts were messed up, making it impossible to install them correctly.  The right solution was to completely remove the wreckage of the old floor pans and weld in brand new ones.  A cut-off wheel on my angle grinder made the basic cuts, but the remaining fiberglass patches had to be cut flooryanked up with pliers and brute force.Fiberglass junk  A very tiring and dirty job.  Once it was finished, though, the extent of rust damage to the floor was clear.  A car just like Fred Flintstone's!  All the corroded metal was cut away and the new floor pans were fit, then MIG-welded in.  This was my chance to learn welding, and Santa brought me a small welder which worked beautifully.  Finally, the floor was fixed correctly and the seats and seat belts could be mounted as Chevrolet had originally designed!

Finished motorA few other minor, but annoying issues were also fixed around this time.  Someone decided that it was too difficult to remove the door locks correctly, so they simply ripped them out of the fiberglass panels.  This meant that you unlocked the car by sticking your finger through the hole and pushing down the lock rod.  Convenient, but not too secure!  The damage was repaired by fabricating and bonding thin metal plates on the insides of both door panels to hold the lock mechanisms, then filling the gaps with body putty.  The factory alarm system was also fixed.  It's pretty much useless, but that was the state of the art in 1976!  I also installed the correct air intake system and valve covers.  The car originally came with chrome shielding around the distributor and plug wires, but these had been lost sometime along the way.  A very generous fellow Corvette owner gave me a complete set and these pretty much completed the engine compartment work, bringing it very close to its condition when it left the St. Louis factory over 30 years ago.

Reconditioned instrument panelMany interior components also needed serious restoration.  Every gear in the speedometer was stripped and the gauge face was badly rusted.  A complete rebuild solved both problems (the only job I didn't do myself).  The tachometer circuit board was fried by running the car without the coil ground strap.  Fortunately, a new board was all that was needed.  The faces of the other gauges were badly rusted; a fellow Corvette owner wanted aftermarket gauges in his car and generously donated his old, fully functional set.  The metal parts of the dash were stripped, polished and re-painted.  Finally, a pair of replacement seats were purchased.  All of these pieces now adorn our guest bedroom, waiting to be re-installed in the car.

The next phase was to deal with the leaking automatic transmission and rear suspension.  The transmission problems were typical on cars of this age and required only some new seals.  On the other hand,
ominous noises from the rear end suggested bad universal joints and rear wheel bearings.  This meant removing the entire rear suspension for a rebuild.  rebuilt rear suspensionCorvettes have six u-joints, and at least half of mine were bad.  Both rear bearings were also junk.  End play in Corvette rear bearings must be set within very tight tolerances using precision-ground shims.  Doing the job required several tools that I fabricated on the lathe and mill, and it was a real learning experience.  I also added the emergency brakes back to the car since a previous owner decided they were too much trouble and removed all the pieces and tossed them in the trash!  When everything was painted and put back together, it worked perfectly.  Nearly all the underside was painted black with a few silver parts for contrast.  Just for fun, though, I decided to paint both half-shafts bright red to add a bit of color.

Christopher JonToward the end of 2006, two events slowed work on the rebuilding project.  The first was the birth of our first son, Christopher Jon, on Halloween.  He is growing every day and will soon be talking.  When only two months old, he was already helping supervise Dad's work in the garage.  Here, Christopher is giving me the "high five" on the rebuilt differential, telling me that it was ready to go back on the car.

The other addition was an 89 Corvette convertible, bought just before Christmas.  We weren't really looking for a second Corvette, but this was just too nice to pass up.  The 89 is known as a C4 style Corvette and has many "modern car" features like fuel injection and rack-and-pinion steering.  Unlike the 76, the convertible has needed very little work beyond normal upkeep.  Cruising the back roads with the top down while listening to the satellite radio is a blast!  The only problem is that I have to share the convertible - my wife also enjoys driving it!

The next major projects for the 76 are rebuilding the steering and front suspension and welding in a new windshield frame to replace the sections damaged by the leaking T-tops.  Once these tasks are completed, the major mechanical work will be finished, and it will be time to finish the interior structure and reinstall the dash, seats, carpets, etc. to bring the car back to life.
