Ahh...The Boat.
I have a 85 Crown Vic. Not at as big as that car...but it is big in its own right.
When I bought it, it was already running, but the speedo was broken, so we reinstalled one of those. Then we pretty much over time, rebuilt the tranny, installed new brake system, ignition coil and module; put a new fender, bumper and header on there as I ran it into a brick wall (but backed up and drove off, no problem!). New gas tank, new exhaust (to make it a dually...that lasted a grand total of 24 hours), new radiator, u-joints....etc.
unfortunately, the car is sitting along side my moms house in northern MN rusting at the moment. Id like it to be a backup or second car for me, but Im not that mechanically inclined. Well, I am...but not enough to possibly figure out what something wrong would be if the car happened to break down.
