Get a set of stock replacement springs from ESPO. They will raise the back of the car, compared to the 50yr old springs you have now. Use the other hole on the adjustable hanger, which drops it 1" I believe ?
Good to go.
Thanks Johnny D. I'm worried how much it will raise it, hopefully not too much. I'm reluctant to get a lower spring than stock, its easier to drop the back than raise it.
