Great thread. Thanks for posting. Are you cutting the metal out with a regular cut off grinder? And did you cut the hole and then trace the outline of the hole onto the new metal and cut the new piece to fit that way? Thanks.

Would it have been easier to just cut out the entire panel and put the new one in? More welding, less fabrication perhaps?

Cutting Sheet Metal
Overlay the new patch piece first and mark where the cuts need to be, use an electric cutting tool and USE GOGGLES OR A FULL MASK ! . .
I didn't *just*once* and now my right eye has steel chips in it that make focusing hard... MEASURE THRICE ! . cut only once or you'll be learning how to butt weld .

Oh I was planning to butt weld everything. I have not looked at how the original rocker panels are attached yet, though.
Thanks for the reminder about Goggles. The inside of auto glass is laminated with plastic film to reduce injury to occupants. That is why the sparks from grinding can melt it. |

Actually safety glass is two layers of glass with plastic in the middle.

Laminated Safety Glass
Only the windshield is laminated, all the rest are tempered and will break into pebbles .
No plastic coating .

Its a half to a 3rd the thickness of the original sheet metal, but welds decently. It does tend to rust extremely quickly, so needs to be well painted.
Some of the stampings are quite worn, body curves might be sloppy and need considerable work to really look good. For the floor pans its great The great thing is that patch panels actually are available for these old cars at a good price

Thanx for the up date .
There are a couple of U.S.A. patch panel manufacturers left, I don't know their names, sorry .

Yes and the windshield has plastic on the inside to protect your face.
I cannot see little metal flecks from a grinder embedding themselves in regular tempered glass. Been wrong before, though. |

My understanding is everyone selling anything for 123s and 126s are selling klokkerholm panels under a dozen different names and prices. They seem to be the world source for old mercedes.

Plastic Coated Windshield
O.k., I'm old so maybe things have changed, please tell me what vehicle has this inside plastic coating because no Mercedes up to 1997 has it .

This thread brings back memories of my 300D rust repair. My car was worse, but in end it was a worthwhile project. As this one will be.
Once the floors are fixed, keep looking! Hood hinge pockets, frame rails front and back, sunroof drains, more that I have forgotten. For what it's worth, check pics in bodywork or restoration subforums. Should be pics still there. Here is the link: Restoration of my 85 300D Shop's pictures here: http://www.lastchanceautorestore.com/gallery_completed/gallery.php?vid=1985_Mercedes_300D Mine in original thread.

A huge undertaking, well done!
In your first post you mention water in the rear foot-well. While the rust from the battery tray in your case can definitely be a cause, keep in mind that on the W123 with no rust issues this can still happen with the cause being a bad windshield seal.

UPDATE
So, I'm in stay at home mode. I could violate the governor's order, but I'm gonna stay put. The garage I'm renting is attached to someone's house and his kids are in and out all the time.
Someone asked a bit ago about my welding setup. I snapped these pictures last time I was at the garage. I bought this rig off a guy on Craigslist about five years ago. The welder wouldn't penetrate anything and I ended up replacing the rectifier. Everything has worked perfectly after that. I run 75/25 Argon/C02 mix out of that little bottle in the back. I've been using .030 wire, but have been wanting to go to .027.
