It's been a while, but it looks to me like an early DG frame.....but with the GT stamp, it could be the series before the GT Performer's. I had one of each back in the early/mid 80's as well as a few SE's, Torkers, D'Back, Cooks Bros, Hutch.....My dad was always gettin pissed at me because I would have a few torn apart in the garage so he couldn't park in there...lol...most I had at one time was 8, that's when I was banned to the back/side yard to do any work on them!
We know exactly where one cow with mad cow disease is located among the millions and millions of cows in America and Canada, but nobody has a clue where thousands of illegal immigrants and terrorists are located. Should the Department of Agriculture be put in charge of immigration??
