Default 76 TA 455 rear leaf spring

Does anyone know what the correct leaf spring would be for 455 TA.
I have a set of 4 leaf, and a set of 5 leaf, both looks factory with the plastic isolators and wrap clamps etc.

Ride height aside, just wondering what would be better for general handling (if there's any difference) for a bit of spirited driving through the mountains

Most TAs were 5 leaf. SBC Camaros had 5 leafs. If you look at Detroit Eaton Spring's site they have rates. If you email then with thickness of each leaf they can even give a ball park which spring it is. Surprisingly most 5 leaf are softer ratesbecause each leaf is thinner.

My personal cornering preference 550lb+ front springs stock rear TA springs and a 1 &1/4 front bar and a 5/8 rear bar and good shocks like Bilsteins. Stickier tires help a bunch also.

There are two schools of thought in play here.

Soft springs stiff sway bars.
Stiff springs soft sway bars.

It has been proven both handle equally well, like when you weave cones, but I prefer softer spring stiffer sway bar because when you dive into a corner the softer spring allows a better weight transfer fore and aft.

Thanks guys, I found a listing for 76, looks like 4 leaf with 2x rates, (126 and 175 lb) I will check out what I have on hand.
Has huge front roll bar and factory TA one for rear, dont have measurements in front of me.
I will go with the 4 leaf pack initially and see how it goes.
