Morning everyone!

I have a question, and any help will be appreciated.

I need new, stock leaf springs for a 1978 non-WS6 Trans Am.

I know it’s a non-WS6 because I have a 5/8 sway bar.

The question is on the spring rate.

Is it 126 or 97? I’ve been talking with some very nice TA owners, and I’ve done some research online, and I’m getting conflicting answers for which one.
Even some leaf spring suppliers have different answers.

According to this website, the Formula uses 97, which is what the base Trans Am uses, and the WS6 uses 126.

I know both are woodwork and give me the same ride height.

I want to use the exact same ones that came off the car.

97 or 126?
TIA
Jim
