I would be more concerned at how the T-tops looked. If it looked factory or like a cobbed up job. When I bought cars at the auction if it had a non factory item I passed. Even a sunroof that was after market I had no interest in those cars. Unless it was an extremely good job that looked factory it always dropped the value of the car. When I say looked factory, I mean it fooled people. This would never look factory since it was not offered so what ever you spend on it you kiss goodbye plus a loss of value at trade in.
