Carlos - measure, measure, measure . . . and then measure again!
If you are bent on going this way, then cut the frame at an angle that matches the drop angle on the rearward clip attachment points. I hung my clip from an engine hoist using a big nylon strap attached to the spindles. It balances nicely in this arrangement and you can move it in and out of your way as you work at trimming the truck frame.
Make sure the truck frame is up on jackstands on level concrete and again, I can't stress this enough . . . measure your stock spindle location exactly (front to back) from a good reference point on the truck frame. Place the Camaro spindles in the same vertical plane. Suck the A-Frames up using ready rod so that the bottom A-Frames are level with the ground and set your height based on this. If the rearward part of the clip is snuggled up against the bottom of the truck frame it will be too close to the ground and you will grind all the chrome off the bottom of your front bumper and drag you header flanges on every bump.
Depending on where you are in Oregon, (I am close to Portland) . . . I might even be able to swing by and give you a hand.
