My first full year as the owner of a 1968 Mustang California Special was proceeding nicely. In April of 2004, the car successfully completed a 2,200 mile round-trip to Nashville for the MCA (Mustang Club of America) 40^th anniversary event.

A month later, on Memorial Day Weekend, the Garden State Region Mustang Club (GSRMC) extended an invitation to attend a Ford Motor Company-sponsored event in Flushing Meadow Park in Queens, NY, site of the 1964-1965 World’s Fair, and site of the introduction of the first Mustang. The response from club members was enthusiastic, so early on Sunday morning of that weekend a large lineup of Mustangs caravanned through midtown Manhattan, arriving at the park by 10 a.m. Besides the GSRMC, the only other Mustang club invited was the Long Island club. Estimates of the total Mustang count was close to 100. My GT/CS was the only one of its kind there.

For Ford, this was a marketing and PR stunt, as the all-new 2005 Mustang, which would not enter production until September, was represented by a pre-production prototype. Ford was looking for photo ops, so a ’64 ½ convertible was staged across from the 2005 ‘Stang. The stainless-steel Unisphere, one of the few remaining relics from the ’64-’65 fair, loomed in the background. A photographer, hired for the occasion, perched on a 10-ft. tall ladder.

One at a time, each owner was invited to drive his/her car across the cameraman’s field of view, stop between the two posed cars, lean out the window, smile, and move on. As you might imagine, this took some time. I used the downtime to take some of my own photos as we crawled in the queue. Eventually, I had my picture taken, and headed home.

Rally brother Steve and I had started to make some noise about possibly driving the Mustang in next year’s New England 1000 rally. With that on my mind, it seemed that the winter of 2004-2005 would be the ideal time to tackle the leaky heater core. My collector cars are usually off the road for the winter, so I would have the time I’d need to get this done.

On a Mustang with factory air such as mine, the heater core and A/C evaporator reside together in a fiberglass box under the passenger side dash. Following the factory-recommended procedure, I began the disassembly that would grant me access to said box. My A/C was inoperative, with zero pressure in the system, so no further harm was inflicted onto the ozone layer when I broke open the evaporator connections.

Much of the dashboard and instrument cluster needed to be removed, so I used this as an opportunity to replace other worn parts (more about that in a bit). Most of the wrenching was straight-forward. If there was a tricky part, it was keeping track of the various color-coded vacuum lines that operate the blend doors. I knew that new vacuum line kits were available, so that was added to the shopping list.

With the box out of the car, my heart sank to see that it was cracked; actually, a chunk was missing from one corner. I also knew that boxes were not available in the aftermarket, so the heater box was repaired with fiberglass matting and epoxy glue.

Along with a new heater core, I was able to order a new foam heater box kit. All blend doors as well as the core itself got new foam seals. Having come this far, I thought better of reinstalling the dash pad, which was warped, and the woodgrain instrument cluster surround, which had lost most of its chrome. These parts were readily available from various suppliers, so new ones were ordered and installed.

Near the end, I worked as long as my patience would allow to line up the new aftermarket dash pieces. Of course, they did not fit as well as the originals. Eventually, I got it to the point that only I would notice any misalignment.

Did the new heater core work? You know the drill: Add fresh antifreeze; turn on the heat; pray that nothing leaks.

Nothing leaked. The car had tremendous heat output, and anyone riding in the front seats would have toasty dry toes. This would turn out to be a huge benefit during the running of the 2005 New England 1000.
