Hi I have not posted here too often. I was recently helping my wife deal with her grandfathers affairs and we were just opening his storage containers to see what to do with the items. One of the containers had a buick in pieces. I do have a 69 Skylark custom so I immediately figured out what it was. I checked the vin and found out that its actually a GS400 convertible. I don't see any other identifying tags on the car. Although I have not looked in all the boxes yet. Don't have the motor or title though. I would love to put this car on the road, especially if it's a stage 1 (highly unlikely but it helps to dream). Don't know if this is the proper place to post this thread also. So I apologize if it's not. Hence I need a date correct engine and help to see how I can register this car. Any info will be greatly appreciated. Also the vin on the car is 446679H156190. I am located in central California.
