Rear ride height without air shocks.

My '66 Barracuda has had air shocks lifting the rear since I bought her. I've never been a big fan of air shocks but the car was running fine so I didn't worry too much about them. Yesterday I noticed the car was sitting at about stock level ride height. I tried to put some air in the shocks but I can hear it hissing and it immediately starts falling back down to stock level.

I'll post some pics of before and after the air shocks went bad.

I need some info (I'm a bit of a novice) on what my alternatives are in getting the ride height back like it was with the air shocks but without the air shocks. I contacted Espo and they can do leaf springs that are a +1 or a +2. I can't tell from the pics if a +2 is going to be to high or if a +1 will be lower than I want. Has anyone used a 5 leaf spring with the +2 inch option? Does it get the rear height at about where mine was?DSC_0603.JPG DSC_2567.JPG
