: Aligning body to Frame

Is there a special technique to insure that the Chevelle body is sitting correctly aligned on the frame when you set the body of the car back on the frame? This is regarding a 67 Chevelle. any help is greatly appreciated.

Once the body is already on and bolted is there a way to check for alignment. I suspect my car may be misaligned by the shop that set it back on the frame.
Any techniques for loosening up the body bolts and adjusting?

thanks

I center it by measuring the distance between the inner rocker, and the frame. After the fenders and bumpers are on, it may have to be tweaked again.

It's hard to tell where it wants to be, before the bumpers are on. The bumpers bolt to the frame, and the fenders bolt to the body, so if the bumpers are off center when it's all back together, the body may have to be moved to one side a bit, to get it centered.

I went thru this process with my El Camino, and my 71 Chevelle. With my 68, I was lucky. It dropped down in the correct location from the start. I didn't have to readjust anything.

My 70 has two alignment holes, one in front and one in back. Driver's side as I recall.

All the chevelles have alignment guide holes. Find them and use a larger punch and your in good shape. The 66-67's I believe have one at the front body mount and in the back rail. Its not to difficult to do.

my 66 had them on the passenger side
will be a 1/2" hole next to the mount at the cowl and just in front of the rear wheels.

I used a 1/2" diameter rod to go thru both holes in the frame (elcamino) and the hole in the body.

The hole actually may be closer to 5/8" as a 1/2", long socket extension that is not a reduced size in the shank fits perfectly.
