M30-31 pickup cab questions

[Vin-tin]

Using my pictures as reference, i'm hoping someone can answer my questions about my truck (M30-31 soft top/non-indented firewall).

#1) How does the seat back fasten? I've circled (in red) the parts "I think" is what fastens it. The 4 clips spot welded onto the cab back and the 2 clips (one is missing) screwed onto 2 wooden slats. Is this correct?

#2) What is used for the lower door bumper? A rubber bumper goes into the hole in that triangular cab brace. (circled in green) None are listed for that purpose in the catalog. I've narrowed it down to a few choices but none are for pickups.

#3) What are those raised oval areas for on the seat riser? (circled in blue).
Are they necessary?

Thanks Bob.
That answers question #1 for me, and tells me not to believe everything in Bratton's catalog.

What about my other 2 questions I ask about. Anyone?

This is what Marco shows for door bumpers.
I added a picture of an original 82B cab that Neil Wilson posted
on the AA site and there is no bumper in that hole. I don't think there
was a bumper there as it would be rubbing on the cardboard door panel.

My truck had a rubber bumper in that hole(Green circle) so I assumed it was original. I removed it years ago and put it somewhere but now I can't find it.
Gary, your one picture shows a 1929 seat riser, not M30-31.
Those raised areas in the rear portion of my original seat riser,(Blue circles) are original, and yes, the wood goes behind the metal. I found 2 pictures of M30-31 truck cabs with original seat risers and they both show the raised areas I question. I'm thinking they might be there to help hold the rear of the seat spring down. If so, i'll need to ad them to my seat riser before I rivet it in. Since no one knows for sure, I guess i'll just ad them to be safe. I wish I had the original seat springs, but I don't.

You are correct, there are bumps. I missed them on the picture. I just looked at the seat bottom and they are there. Posted another picture above. My bad.

Thank you. Great pictures!
My question isn't whether they're there or not. I'd like to know "why" they're there. What purpose do they serve?
If you read my other thread, https://www.fordbarn.com/forum/showthread.php?t=158859
you'll understand why i'm asking. My truck was completely blown apart when I got it and i'm trying to understand how and where things "fit". Most of the floor on my cab I built from scratch using what was left of the original parts as patterns.

I have no idea why they are there. I just removed the seat back and looked at the rear/back bottom of the bottom cushion. The seat frame is seated at the rear of the seat support up against the vertical riser. The width of the spring seat frame is narrower than the seat support so the bumps are not supporting any of the seat bottom.
My seats are new Labron-Bonney. They fit the seat frame nicely.

I don't believe the bumps serve any purpose either.

If you look at the under side of the door, you'll see a bracket/clip that should holds a rubber block. Many are rusted out. That block lands on an inclined surface on the door sill which shows on BobC's picture in post #5 just forward of the triangular brace with a hole in it.
I'm sure you will see it if you get down there. On my P/U, I played around with the thickness of the rubber block and stuck some leather on the door sill till I got it so the door was tight on it when closed. (Test with a piece of paper. Hold the paper over the sill and closed he door. You shouldn't be able to pull the paper out)
Mine is a driver, not a show car so these little things don't bother me. It worked well - might be worth a try.

Thanks. That's the answer I was hoping to hear. That will save me the trouble of pressing then into my seat riser.

Thanks. I have 2 new clips waiting to go on as soon as I get around to working on the doors. Both need lower patch panels.
