I have never seen a 75 bird with 5 leafs, BUT ALL the Camaros except the Z had 5 leafs. thats the big difference between the rears, as you said taller perches.
I have a 1980 WS-6 rear in one of my cars, and its a 4 leaf perch. Just checked a '79 I have, 4 leaf.
2.56 with 5 leafs in '75. I would have never guessed Interesting!

Remember it was a 350 Esprit with base suspension, not a Formula.

Interesting chart. Gramma's car had "PC" listed on the broadcast for rear springs (right and left). Chart shows that as 5 leaf, 97 lb rate, part number 480880.
