One half butt sag repair

Art....   Yes you can do just the one side, but while you are doing the job, its not much more effort to insure the other side does not sag later.....    Before you dive into the rear end, check the area over the front beam to be sure the nose section support was installed.....   (ask me why I ask you to do that!!)    

Here's pic of front beam

On page V-4 and V-5 I see reference to lower front body support and top body support, looks like angle iron that is bolt on top of the front beam. As you can see there is nothing like that bolted to the top of my front beam.

I ASSUME THIS IS A BIG PROBLEM?

There is 11,000 miles on this car, how come nothing has gone wrong. What should I have noticed in driving this car? I have put less than 100 miles on it.

Can't seem to load this pic....

Finally.....  This is what I made to act as the front support....  On top of the beam risers are tapped holes....I fitted these with all-thread rod stock....  The rod stock passes through  two pieces of pipe.(the short piece slips in to make installation simpler)   The flat bar on top is 1.25W. by .188Thk. with two pieces of .125 rubber on top to cushion the fiberglass...

When installing, the all thread passes through a hole in the trunk, the rubber, the steel flat bar, the pipe sections, various flat fender washers to spread the load, and then threads into the risers....   Hope this helps....

With out this support strange things can happen to door gaps and such...usually the gap at the bottom of the door....

Thanks, sounds like I can handle this.  What size is the rod stock?, must be metric?

And you do both beam holes with one long piece of bar stock, or each hole a separate but same process, (I can not tell from the pic) 

Would a matching piece of bar stock in the trunk side help with the load? Or fender washers suffice?

Thanks for the help, and the quick of thought to have me check this!

The rod stock was SAE for my car, but may be metric on others.... One piece of rod stock per hole with fender washers inside the trunk area was the method I used....   Use nylock nuts in the trunk ....

That front support holds up the entire font of the car that is not supported by the cross-member behind the dash and the front bulkhead (firewall).  Little wonder a lot of CMC's get stress fractures near the headlights and have issues at the tops of the door openings.

Put in a front brace THEN do the butt sag remedy.  Your right side may be fine, but drill out the rivets (one at a time) and replace with bolts AND some Loctite construction adhesive and you'll be good for coming centuries.
