Model T Ford Forum: Forum 2015: 27 Runabout seat back rest
Top of pagePrevious messageNext messageBottom of page Link to this message  By Eric Sole - Castelldefels (Spain) on Sunday, May 10, 2015 - 06:57 pm:

I'm changing out a homemade interior and incorrect seat springs with proper ones.

Currently the seat back springs just rest against the metal of the rear body skin, there is no wood structure there.

I saved this picture off the internet recently but don't remember who published it.


I have seen others with horizontal pieces running across the three vertical ones. Can anyone confirm if this setup is correct for the 27 Runabout and if so, provide the measurements of the wood pieces?

Thanks for any info you can provide.

Correct factory method.



Don't know of any drawings with dimensions of the wood pieces, but simple to do, as the metal pieces will have the old stove bolt holes. Make the rear seat wood first, then the uprights run to the wood pieces of the tack strip around the top edge of the body.

Dan, there are holes in the body for the two outer slats to fasten to at their upper ends, but nothing for the center one to fasten to.

The factory price list shows a "Connection (Trim Rail)" PN 45141X which appears to be a wooden tack rail running along the inside of the body. This would give the vertical slats a place to anchor to.

I can't tell if it is only as wide as the outer two slats or if it continues to curve around the sides of the body.

Actually, I'm not even sure if these two holes were made at the factory.

Here is a photo showing the back framing from plans that are around.

Eric,
The holes that show in your photo are not original and should not be needed.

Beautiful! Thanks Jim.

That confirms the "Connection (Trim Rail)".

I can see I'm going to be sitting a lot closer to the steering wheel than before...

Jim, what's the car's body color on your profile?

Eric,
The color is similar to the maroon color that was offered in 26/27.

You could use a foam pad and plywood instead of the back rest spring to keep from being crowded against the steering wheel.

The wood piece ("rail" #45203X) {Price list of Body Parts} is stove bolted around the top outside of the body, on the flange.

The yellow marked piece in your post.
Those 2 'holes' in the upper part of your body have been punched there for some reason. Perhaps some owner thought the turtle deck was rattling and fastened it there!





Look in the Body Parts book at the '26-'27 touring rear seat, it is constructed similar to the runabout front seat.

The "connection" is a small metal plate that reinforces the wood rail. The wood rail is support for the rear of the backrest and as the tack rail for the back rest upholstery and the top.

The rail is actually strips (curved) 4 pieces which are fitted.

Then the center uprights (frame #48056X center, frame #45056X right, and 45057X left) are stove bolted to the rail.

The bolt countersunk head goes into the wood rail and passes thru the wood, thru the metal flange, and then square nuts are placed with lock washers on the wood uprights.

Stove bolts are mounted to the lower wood rail on the rear of the seat cushion meta/ piece running along the lower part to hold the end of the uprights.

This view may help if you look closely.





And this showing the 'rail' wood which is the upper body tack strip.






This view shows the 'rail' from the outside, and where the center of the old rail is broken, that is where the "Connection (Trim Rail)" PN 45141X is mounted on the inside. It supports this important place where the rail pieces meet, and where the most strength is needed.
