Yes, the decals are still available from Slixx.
The McEwen car was rebuilt and then driven by Fred Goeske, same guy that drove the only 69 Road Runner funny car, and the car eventually ended up in the Don Garlits Drag Museum. A few years back, the cars owner came for it and Garlits would not let it go, but, eventually relented and the owner got the car back, minus the engine. I assume the car in is currently housed in some collection and who knows when it will be seen again.
