I pretty much buttoned up the left rear frame replacement and floor repairs.  I swabbed it all pretty good with POR-15, primer and paint.  

I also installed LMR torque box reinforcements on the driver's side.  I didn't know 23parts.com sold lower reinforcements until after I'd started working on the LMRs.  The 23parts would have been much easier.  

Now I have to take a pause to do some home maintenance and punch-list items on my Torino.  I hope to be back to the TBird by mid-October.  

Next on the list:
-patch the RR frame rail
-repair LF torque box
-install subframe connectors
-replace left quarterpanel

Talk to you all in a couple of months.

I've been gradually getting back into the rust repair on the chicken.  I surveyed the right rear frame rail.  It is not nearly as rotten as the left side was.  In fact, the only bad parts are the pocket where the quad shock mounts and the very rear stub where the bumper attaches.  So, I decided to use a LMR Mustang repop rear frame rail as my donor.  Once again, the shape of the curves in the rails is spot-on.  It's just that the Mustang rail is about a foot shorter.  

I cut a little less than 11" out of the old rail and cleaned the metal for welding in the new.

The red template was made using the original rail.  You can see it overlaid on the Mustang rail.  It's fortunate for me that the cars are similar.  

On the second pic, you can see how the rust is bubbling throught the side of the old rail at the quad shock bracket.  It was more than likely okay if I don't autocross the car, but I couldn't leave it alone.

I finished the repair of the area where the quad shock mounts over the weekend.  I butt welded the new segment to the old rail.  Then I used scrap from the LMR replacement rail to reinforce the joints.  I think it should work well.  Torque is the test, though.

       

Next part is patching the rust on the rear rail stub where the bumper seats.  This won't be too challenging, but there are several small segments of 14 gauge to make work.  Once again, the LMR rail will provide the raw material for the patch.

The rear axle stub is repaired but I have to patch the sheetmetal on the end panel.  Getting there.

Now I'm working on installing the subframe connectors.  I have the Griggs lower bar installed on the passenger side.  It lined up very well.  As you can see, you have to cut a lot of the floor to seat the upper connector.  For me, there is lots of metal cleaning on the front of the rear frame to prepare it for welding.  It's tough to get inside it to clean well.  So I've dosed it with Ospho a couple of times with lots of wire wheel and cup work after each dose to get to cleaner metal.  That, and patching lots of small areas with pinholes to make the cab watertight.  Now I'm waiting for some extra pieces from Griggs: a bulkhead plate (doubles thickness of floorpan at vertical portion where upper subframe goes through the floor and into the rear frame), some gussets from the rear of the connector to the rear of the floorpan, and some 1/8" tabs to connect the upper and lower connectors in their centers.  They're in the mail, so hopefully that will allow me to complete installation.

Sorry for the lack of updates.  I have the passenger-side connectors installed.  It's pretty beefy.  I have some ideas to do better on the second set.  Mainly, instead of cutting so much of the original floor pan off to make access to the front channel, I will bend it back, place the upper connector, and then fold the floor pan on top of it and spot weld it on the top, too.  

The bulkhead plate that welds underneath the rear seat took some time.  It is 1/8" plate.  I had to slowly tweak it with a 24" pipe wrench to get it to mate well against the existing floor pan.  

Then there is a 1/8" gusset that connects the rear subframe to the connector and the floor pan underneath the car.  

Now, it's time for the following:
1. patch right rear wheelwell
2. patch LF toeboard and cowl
3. install L subframe connectors
4. install Maximum Motorsports panhard bar

That should keep my busy this spring and summer.
