  View original topic: How would you handle this pan....
Jeckler Sun Nov 02, 2008 8:33 am

On my '63, the outboard seatbelt mounts are in the pan, not the body. On the driver's side, there is some rust through from just in front of the rear seat, to about a quarter of the way under the front seat. I'd like to keep the original belt mounts, mainly so that it matches the other side. I'm wondering about the cost and strength of butt welding a replacement in, versus replacing both pan halves, even though the passenger side has no rust, just 10 1/8th in. holes drilled in the battery tray (for drainage I presume). I got this pic of a passenger side from the gallery, and the red line indicates where I'd cut and replace.
The reason for the butt weld is because I don't want the repair to be noticable, and I think a lap weld will stand out like a sore thumb.
Thoughts?

i would weld the holes up ..grind them ... and then por15.

That's the plan... on the passenger side.
Let me clarify. The pic above is what would be the driver's side on mine, and is rusted out.

Weld the repair panel in with butt joints. Replacing the entire pan half, transferring the seat tracks and everything will take a long time. On an area that collects water like the floor pan, a lap joint will rust out fairly rapidly.

Andy, if the weld is under carpet, only you will know. It's your choice on the type of weld. I don't agree that a lap weld will rust out fairly quickly. If you prep everything correctly and weld correctly, there is no place for water to seep into. If you are getting standing water in your pans, you have a larger problem that needs to be addressed.

I don't want it to be seen from under the car. Of course it won't be seen under the carpet. The car is at the start of a full resto, mostly original, hence why I don't want to replace the full pan half and have it not match the other side without more work.

Butt weld it is. On the clip I'm replacing, I weld both sides. If you lap weld and the body is off you can put the chassis on two wheels to weld underneath. Running a nice bead over the lap and grinding it smooth would make it look like a soft ridge. POR15 over it and I bet no one would ever see it. You are right that a butt weld and POR15 would be even less noticeable.
