Purchased Camaro last year and noticed when I unloaded it the car was lower 3/4 inch on passenger side. When I got under it I could see the mono leaf was shot. Installed new coil springs in front and new multi leaf springs in back. Sat it back down on lift and it still has .75 lower on passenger side. Hoping for suggestions. I was wondering if the front eye of leaf springs are suppose to be torque or tighten and back off like a wheel bearing? I have sub frame connectors but I'm hesitant to put on until this is corrected. Any thought or ideas. Picture before new leafs

 

But I bet once your butt is in the drivers seat, the car may be close to level. To make sure one of the leaf springs aren't preloaded, loosen the front bolts and the upper/lower shackle bolts, bounce on the rear of the car a few times with your body weight, and re-tighten.

 

As I look at the picture, to me, the rear window and gas tank appear parallel and level and body is leaning down on pass side?

 

It kinda does, doesn't it. Thinking panel replacement perhaps, and left side was installed a little high in back, or right side a little low?

 

If jousting the suspension like Camaro 69 suggested does not work there are 2 common issues that can cause this issue with a rag top.

1. Car was over stresses and twisted. Your first gen camaro is flimsy. In a hard corner the car will ride on 3 wheels as the body twists. Turn it hard enough with upgraded tires and it can bend. This twisting is much more common on a car that has had its center (or X) brace removed. Even jacking up the car with a floor jack can twist the car without the center brace installed. Many center braces are removed for exhaust clearance, People think they some type of heat shield and not needed.
   
   This type of damaged is easily corrected on a frame machine. I would then recommend some type of under body kit to stiffen the body unless it is becoming a show baby. Once it has bent its more likely to re-bend.
   
   
   This is why GM never build a 1st gen Z28 rag top. Marketing wanted one but engineers said they would not make it out of the 1 year warranty without twisting on track condition.
2. Body was restored and not put on a jig. When you do serious work on the floors or rocker panels on a rag top the body should be mounted on a jig. The floor and rockers are the frame on this car. On none rag top the floor and rockers are not structural so unless the metal worker knows this it would most likely wrong at some level.
   
   
   Of the two issues this is the worst because depending on how far things are off the frame machine could break welds and tear metal when trying to get it back into Spec.
