This is my first posting on the site. I just found it earlier this week and it looks like there is a lot of expertise out there so I hope someone can help me out with my question. I have just purchased a 1973 L-82 coupe with what is supposed to be 18,000 original miles. The car sits visibly higher than other cars of this model. According to the 1973 GM Service Manual the car is about 2 inches higher in the front and an inch higher in the rear. These measurements were taken with the car sitting on 60 series tires and not the 70 series tires that were original equipment, so overall the car is probably even higher than it appears. My questions is if there is a way to determine by physical inspection if the car has the Z07 suspension and brake package and if the car would sit higher than normal with this package. The car came from the factory with no A/C, no P/S and no P/B. The seller says that he has the original invoice but he is still looking for it. I do not know if the build sheet is still anywhere on the car or not. The seller also gave me (what he claims) are the original tires which are Goodyear G-60 Polyglass tires. The spare has never been on the ground and the sticker is still on the tread. Once again, the Service manual says that the original tire was a GR70X15 and that there were no optional tire sizes. Any information would be appreciated. Thank you for your response.
