bench seat differences

[chris71]

my 71 bench seat is pretty bad, totally stock but just sucks, when you sit in it i feel like i am leaning towards the door. its a spring bottom.

just for clarity (correct me if i am wrong):

67-68 had full foam bottom and spring back (and had tilt forward back option)
69-72 full foam bottom and back, but some seats had the spring bottom (rigid non-tilt back)

i remember siting in my fathers 72 and it is pretty comfy, i think it has the full foam deal.

where the full foam seats for 69-72 an option? or just different plants did what they felt like. the price of seat foam in LMC was $500 WTF!!!!! i am thinking of maybe picking up a foam seat from a junkyard and recovering it if the foam was still intact. any other options you guys can think of? i am trying to stay with the stock look.
