SAh1081 Rear springs

Ok, I've decerned that the PO put competition springs on my car. SAH606 in the front and SAH 1081 in the rear. I know the fronts are 390 lb but I cannot find a weight for the rears, does anyone know what those springs are rated at?

Those numbers made me cringe, same as the TRF springs which didn't work out for me. They were exchanged with TRF for what I know to be Goodparts which are 470 lb.



Found these notes, not sure who made them but they raised the car way to high. 20% stiffer was the only number they gave.

SAH 1081 11 3/4", .535 coil, 3 13/16" dia., marked with red and green dabs of paint. Says uprated 1968-1972 made in USA on sticker.

SAH 606 10 1/8", .541 coil, 4" dia., slightly thicker due to rubber coating that the rears don't have.
Says comp. grade made in USA on sticker.
