Welcome to the Stovebolt cooterdude. Looks like you have a corral full. I bet you have a hard time figuring out which one to drive
Speaking of buicks, I was looking at some old tin yesterday and say TWO 53 Buick's in a guys "salvage yard". He said he'd take 1200 for both of them. I didn't get a good close look but I think they are worth the money. Both straigt 8"s If interested I can hook you up.
