Technical Seat mod help.

Anyone who can advise on HOW to move a seat back.. to make room for comfort and safe driving in a ‘29A Coupe !
What needs to be done .. welding/fabrication involved ??

 

Rear package tray between back of seat an rear cab,if still there can-be taken out,use the extra space for moving seat back/ this some seats,need to be cut down[ to wide] and or made thinner,plus base need to be lower to floor if your big. There are FATMAN streeingwheels that fold up temp when getting in or out too. Mock up fit,is your buddy,tell get it right< no wasted time doing as much of that as needed.

 

In my '31 A Coupe I took out the "parcel tray" that was between top of the seat back and the rear of the cab. I then slid the stock seat back on the riser and made an adaptor to mount the seat to that then mounted to the stock seat riser. If I recall that moved the seat back about 4 inches or so.

 

Yeah, skinny little old dude now, having just had 5 back ops !
Even at that, don’t have room without mod. Does tray go back in or no ?
Thanks Rick.

 

No tray goes away.

 

Hey ric, your input will help for sure !
Did you dump tray .. trim it or get rid of it ??
Thanks Rick

 

I took it out completely. Moved seat back to the rear of the cabin.

 

A lot of springs and padding in an original seat,
- have you considered building a new one that is thinner in seat and back rest, or modifying the one you have ?

 

I've done it about 5 times. So here is a general run down.

So you have to remove the seat completely for starters. Remove Package tray.

Note the step up for the foot pad for the rumble seat will need to be flattened out, so no step up behind the rear of the seat if there is one.

The riser that is welded and rivited to floor needs to be drilled and removed in one piece. You will need to add a cross piece between the subrail about 2" back. This I suggest a piece of 1/2" x 2" rect tubing or something like that, even a small c channel but needs to be about 16 gauge thickness. Long enough to go from side to side, joining the subrails on the sides.

Side note: You will be amazed what 2" will gain you, if you have over 30" inseam I suggest 3 to 4"

I would tack the cross piece in, tack the riser to it, and then put the seat in to see how that works, Test fit your seat and see if you have enough.

Once you are there, weld the cross piece in, re weld the riser to the cross piece, and you only have to make two small pieces for the rear of the riser to fit on the subrail again. If done right and you keep everything straight and true, the adjustable seat base will still work for future drivers of shorter statue.

Just a pic of my coupe before I ripped it out completely and put a mini van seat in it. Note, I didnt have anything other than the riser.

 

also. If you redo seat, add foam along front edge of seat base. this will help with leg room and support leg.

 

Removing the package tray is a common practice with the Model A Coupes and the Deuces, you gain a lot of room. HRP

 

Feel like the RCA dog?

 

Thanks Mr Stubbs !
I was just loaded down with hardware, so can’t do this mod myself. I’ll show your input to a guy who can do !
As usual, you HAMB guys are the BEST !!
You may notice an auto trans (slant 6) behind the B type engine. It was auto or maybe no drive at all… bummer but still trying.

No problem man. Best of luck with it.

Nothing wrong with some aftermarket parts to keep the body going...

 

Hello,

When my brother and I bought a old Model A coupe, our thoughts were to make it into a dual purpose street daily driver and weekend racer at our local Lion’s Dragstrip. we knew something was going to hinder us as we sat inside the cab with the stock seats. The two teenagers did not have much “wiggle” room. We were not huge by any standards, but for young teens, two of us in a small cab like the Model A coupe was going to be a challenge.

Our friend’s 34 Ford 5 window coupe seemed larger and when two teenagers were inside, had plenty of room for stretching out and relaxing on short road trips. But for us, we were already looking into small sporty car bucket seats like our friend little red car. Those seats were not only comfortable, but smaller than most seats. They also adjusted the back in many different degrees of comfort. Not so on the Model A seatback. Or, for that matter, at the time any Detroit stationary seat back that only went forward and back.

The smaller sporty car bucket seats look good, are very comfortable and adjust to any size body type. So, we knew our local junkyards had plenty of those adjustable bucket seats. If and when they were to be installed, they would be moved back as far as possible and set up so it would still be comfortable.

We sold the Model A within a month and the next time we considered a bucket seat installation was in our 1940 Willys Coupe we started to build for the B/Gas or C/Gas class competition. We selected those smaller sporty car seats and could adjust them to fit either brother, behind the wheel or as a passenger.

People are still in the standard bench seat mode and if that is the case, they take up the normal amount of space. But for folks in the 5’9” to 6 feet height and proportioned body style, will cramp most comfortable driving positions. YRMV
Similar style sporty car bucket seats with adjustable backs. they had their own bottom of the seat mounts that did not take much to adjust and install...
