Gundam Pilot, you have a Dozer too! I bought mine 15 years ago from Sturgeon Bay, WI and that game gets played the most at parties.
The only issue I have is the stupid scoring mechanism that I cannot get working correctly no matter how many times I take it apart, clean it, or swap out parts.
If yours works would you consider folding the back down and taking some pictures of scoring mechanism...I may be missing a spring or pieces, but since there are very few out there it is nearly impossible to get help with fixing them.
I also don't have the 8 track player with mine, but the wiring is still in the cabinet for it if I every wanted to track one down.
