Wagon parts possibly needed? Checking before I buy the car.

Thanks for the info and help. An old school hot rodder somewhere stuffed a 400bb in this thing using and motor plate and stock manifolds. The trans tunnel and firewall has been modified and the heater box deleted. It's a cool car but not done the way that I would have preferred it be done if you know what I mean. Weighing he pros and cons before the purchase.
