You did the right thing, these cars are getting hard to find, mine rolled out of the paint booth Dec. 24th, 1988, and still looks like the day it rolled out. Fortunately it was an Az. car and had never seen salt or snow, and still has the factory undercoating on it. I've owned it for 22 yrs. and wouldn't sell it for any reason. You will be happy when it's finished right.
