Hey Mark,
I have a whole bunch of pictures of 1980 TOC sleds but only a few of the 79's. The major difference between the years (other than Black vs. White) is that the 1979's used the Intruder style decals but the 1980's used the Invader style decals in white on the cowl and green later style stripes on the tunnel. I say go for it. Your not gonna (nor are you trying to) fool anyone, but you will draw some attention to our passion!
