I am in the process of re-wooding the '26 Touring.
Working my way from the front to the back.
So now I have the board for the front seat in place. It needs some screws and I noticed that the body is missing a couple of screws as well.
Please see the picture of the passenger door jam and the seal plate.
The door jam looks like I need tree screws. Two the same and one for the wood.
I will have to do the same process on the drivers side.
What screw size do I need for the body and what screw is used to hold the wood in place.

Also would like to know what screws are used to keep the door seals in place. The Phillips screws currently in it need to replace and the rest of the holds need to utilized.

Here are the pics.
Thank you

Just can't remember the thread size, either 8- or 10-32, but the sill plates fit with oval head screws into captive nuts in the frame rail channel metal. They are fine thread captive nuts for machine screws, but size them with some variety of fine thread screws and you can find the proper size that way. Used stainless steel oval head from Restoration Supply Company on the polished-up original zinc sill plates on the '26.

I just completed this chore on my 26 Touring but used aftermarket sills. My holes were mostly stripped out on both the front and rear sills. Where I could, I simply used a nut and screw. Some nuts I had to use EZ Turn on the tip of my finger to hold the nut and get the threads started. Took a lot of mechanics gymnastics. I believe the frame is drilled and tapped for #10-32 threads. Some of my front holes worked without nuts. A few holes where a nut wasn't possible, I bought a riv-nut tool to set in some new threads. Under the front seat pan I had to buy a small riv-nut tool you can see in the pics. If you need a positive ID on the threads and more info on the riv-nut tool, let me know. I used oval heads rather than flat.

The aftermarket sills required some mild cutting and bending to fit right.

Good luck!

Oh, I ordered from Bolt Depot and also got stainless steel screws.....

By the way, EZ Turn is sticky and great to start hard to reach nuts.

I just bought a bunch of vintage looking square head bolts and slotted screws from black smith bolt and rivet supply. very nice hardware and very reasonable prices

The Bolt Depot is a great place.
Once I was able to figure out how to navigate the site to the slotted screws.
Thank you very much. Now I just need to get a total number of screw needed and place the order.
This will get my Corona Puzzle moving again.

Just double check the thread size. I used different thread sizes on my project so I could fit the riv-nut inserts, nuts and threads in the frame.

Any idea what size screws that I need?

What I am going to do is stop by Lowes or HD and get a bunch of the small packets. Use them as a guide.
Then I can place the order and just need to get the approximate length that is needed.
This will eliminate some of the guess work.

Good idea. I had some that weren't quite long enough and had to make another order but I can't recall the details. I would have to run out to the garage and see if I can find the package label. My approach was to buy many different sizes and thread pitches and mix and match as needed.
