Nice car Tom. Kind of shocked of the mileage ya get out of such a large engine(and heavy car). I'm too used to 10-20 out of my vehicle's.
('01 Cherokee, '94 Burb, '87 Dakota, '90 Wagoneer) and they've got nowhere near the ci your engine has. I wonder what that 2v 351M in my 'future' Torino Wagon can get?
That thing is still new....for being 39 years old!
Can you possibly get your speaker's rebuilt?
