I am looking to buy a clutch kit for the A523 3.77 transmission, I know it uses the same clutch as the A568 but there are some options out there and I'm not sure which one to buy. There's Standard clutch kit that is made by Alto USA, Valeo, Sachs, Luk, Exedy and a "Duro" clutch kit that uses Valeo clutch disc. Are all of these similar or is there really a big difference? I can get the Standard (Alto) and the Valeo really cheap, so if that would hold up fine for 18psi I will take that.
