It looks like after reading what Satellite sent that it all comes down to what people really like for themselves.
I don't mind the harshness of my 65' because its a purpose built animal, but I guess if I could not find originals (strange being that these particular cars are not really that old) I would settle for the aluminum types.
I will admit that at this point, this car does wander a little and it makes me nervous on these crowded highways of New York. Perhaps it may be because it needs a complete overhaul of the front and rear suspensions (which I do with any car after a purchase) or it can just be a design imperfection of that era car.

I've since ordered the rear leaf springs, Isolators, shackles and bushings and U-bolts. The only items I am on the fence about are the shocks. I hear that the Bilsteins are the ticket but that the KYB's can be a bit hard.
Thanks guys since I am new to this breed and year. I've always loved the 71' 73' Chargers and Satellites.
