Latest pics.
- Patched the rear right floor and re-attached the bumper bracket.
- New right rear guard is clamped into place. Need to get an outer wheel arch and patch between the side of the trunk floor and guard.. then I can weld the guard in place.
- New cowl side panels welded in to both sides. Now just need to have some angle made up to replace the front of the firewall where the cowl attaches and I can weld the new cowl in place.

Looks like I’m going to have to replace parts of the inner guard on the right hand side.
Need to check the left side too now. Hoping its okay, otherwise the left guard may have to come off too.
Put the new rear cross member into the boot that supports the rear of the tank and the tail light panel.
Also have to patch some of the boot floor on the right hand side.

Latest pictures… the more I dig, the more I find
I need to take a trip to the tip…. my garage is filling up with discarded mustang parts!

Repaired the side today.. my first attempt at a visible panel, so I hope its good enough to be able to cover with a small amount of filler.

Todays update… got the cowl out. What a job
Got some repairs to do to the firewall before I can weld the new one in.
Need to get some angle made up to remake a fair amount of the front edge.

Got the floors finished now - at least from the top. More work to be done underneath I’m sure when I flip it over.
So we went from this:

To this:

Some of my welding still needs work, but its mostly because I’m not cleaning the area properly first
I think I will fix the bad ones with the TIG later on. I’m much better with TIG than MIG.
My next nightmare…

And this side I think I will just buy the rear right replacement panel rather than trying to repair.
