I got a little high tonight.....

I guess you did something similar at the rear. To jack the car up that high did you used some blocks on floor jacks?
Gets a little squirrelly if that’s what you did doesn’t it?
I have raised a B body up about 32 inches and put it on 12-ton jack stands.
If you are planning on taking framing members or sheet metal out, shore up the mid section just in case so things don’t shift.
You probably thought of that.
