This exercise is another reason to try to get the correct part the first time from you favorite Delorean vender. An innocuous little part like a gas cap is an interegal part of the fuel and emissions system. By substituting what looks like the same thing can put you and your car at risk, at the least it could cause you to fail an emissions exam and sicken you with fumes. There is no reason to pursue the search for a substitute when there are a sufficient quantity in stock and probably cheaper than finding the wrong one 2 or 3 times and then having to modify it.
