Default Leaf Springs

My 67 S-Code GTA has 4 leaf springs and my 67 6cly. has 5 leaf, why does the GTA have 4 leaf and the 6 cly. have 5 leaf, seems like it should be the other way around, the GTA has the original springs in it.

It isn't necessarily the number of leaves as much as the arch and stiffness in each leaf. Many early Camaro's had monoleafs.

The simple answer is your 6cyl car had the springs replaced previously. They all had 4 leafs.

All 64-73 Mustangs had 4-leaf springs, from the little 64 170 coupe to the BOSS 429 NASCAR.

If they all had 4 leaf, what is the spring rate difference from a 6 cly. to a V-8 car and how do you tell what you have?

Much less difference than front springs, something on the order of 610/650. The weight on the rear of the car was pretty much the same on V8 and I6.

Unless you can find a part number on them, you pretty much can't tell them apart.
