Thanks B&G, but I bought the car with the spoiler on it... I may, and I May not have put it on anyway (probably not?) as I like the stock Pontiac letters and the 400 emblem.
And the car is FAR from stock, so there are so many changes, that the Speedo, is just about as close as it will get. I prefer to have the wheel wells stuffed, instead of all that dead space.... and the 15" gives a buch better ride and better performance. And with the 4 wheel disc brakes, and upgraded suspension, there was no way anyone could stick with the 14" wheels and tires...
And that why I love this board, everyone has thier own idea of "The Perfect" Firebird... mine is still undergoing transformation... but it's the way I would have odered my car built, if I could have... and that's the way it should be if possibel (sans rare, or close to original cars)
