Here is a rough looking 1988 GT Avalanche. Its a interesting bike, GT pulled out the stops for the bike, See my page on the 1988 GT Avalanche.
This rough example is unfortunately not complete with with a few components not correct. namely the Rear Derailieur, Front Brakes, and the Pedals.
During Restoration: I stripped the bike down to the frame, and managed to get the Neon Paint off of the frame (although the graphics took a little bit of a hit, they were bad as you can see in the pics above.
The cranks and rest of the components are being cleaned up and re lubed, and will be going back on shortly.
