Yikes, I thought that Eaton's were the way to go, for a reproduction spring anyways..... I don't know if I need to get my original leaf springs re-arched or not. When we started to restore the car, the engine, trans, hood, fenders and such was already removed from the car. So I don't know what the ride height was like before we started. And, I didn't even think about measuring the ride height anyway.
