I have a 1984 mark 7 and a wrecked 1989 mark 7 What is of value that will fit my 1984 and should be taken off the '89 before it is scrapped?

You should consider removing the engine and transmission if they are in good condition, as they may fit and provide valuable performance upgrades. Additionally, the suspension components, such as the control arms and brakes, could be compatible and offer improved handling. Interior parts like the dashboard, seats, and electronics might also be transferable and enhance your 1984 Mark 7. Finally, check for any body panels or trim pieces that could be in better condition than your '84.
