So here's the differences I've noticed between the two seats.

1) (This one is obvious) The Palomino (?) has a five-pleat pattern and the blue seat has a six-pleat pattern; before 1984, only leather seats came with six pleats.

2) This one is less obvious but interesting. The Palomino (?) five-pleat pattern only has springs on the sides:



The blue six-pleat had two coils in the front along with the side springs:



Are these front coils something that came in in 1984 in general? Are the front coils something that went with the six-pleat style? Is the seat bottom from the Palomino (?) seat really from an older car and are the front coils something that came with the mid-generational refresh? Does anyone have any thoughts?
