My 56 never came with the original seat, so I'm clueless here and need advice. I got this seat from a member out of his 54 F100. It has the tracks and all. I removed the tracks to clean them up and paint. I looked at the mounting holes on the floor of my truck to see where these tracks would mount. I noticed each end has two holes side by side. The floorboard also has two holes on the hump on the floor in the middle of the floor board. The tracks measure 20.5", hole to hole. Measuring back, it appears the track would mount directly underneath my fuel tank. I pulled the carpet up and there are no mounting holes there? I did notice that there are a few holes where someone mounted a box for my present seat closer to the hump I mentioned earlier. Its actually almost in-line with the seat belts. My question is this. Since my truck is a 56. Will the 54 tracks fit? Or are these tracks out of a different truck? I was wondering if some of you guys running stock bench seats could see where your trucks seats mount and let me know. I guess I could cut the tracks and redrill holes to make it fit. Any advice would be appreciated.

 

Ed,

My 56 F-250 seat and cab are in storage right now, but I'm looking at the tear-down pictures. The seat rail mounting holes in the cab floor look like the two side-by-side holes you mentioned. The front set is on the "hump", and the rear set is almost at the back of the cab, right under the gas tank.

Here are a couple of photos that sort of show what I'm talking about. I don't have the measurements, but I would guess that it's close to 20 inches between the front and rear bolt hole sets. I have high-resolution photos if you want to see them. I don't post the big pictures on-line to keep the message download times reasonable.

I just measured my 56 and they are 20.5 inches and they do mount under the fuel tank (or where mine used to be)

On another note "Welcome back George". Now get busy and mount those running boards.

Thanks guys. The seat that's in it is from a 48 Ford. It's too small length wise and is mounted on a metal frame which bolts into the floorboard. I noticed in Earls pictures which are real helpful, the holes are behind the metal plates sticking up and are closer further to the middle? Someone must of had a different seat in my truck before because there are several holes in the carpet and floorboard which look like they may be for seat or seat belt. I'll pull the seat out and see what I got. Is there a special type of bolt that goes in there? and doesn't it mount from underneath the car?

Merc- your measurements are exactly the same as the length on my seat frames. Looks like these are the right ones and will fit. Sure look funny when your looking at it with the carpet and seat installed. I'm going to pull the seat and carpet and see what I got there. The seat is going in for upholstery soon. I tore the tracks apart and cleaned them all up. Wanted to make sure this bench fits before I pay money to have the seat re-upholstered. Thanks George and Chuck for helping me out.

I might be wrong. I have a 52 Panel and a 58 Pickup. Was the gas tank for the 54 mounted under the cab? Like I said I might be wrong, but that might explain the difference in the mounting holes. Could you use the mounting brackets from the 48 seat? I don't see why it would be very hard to make it fit. Good luck, John (Black58)

 

Black - I believe the 53 had the tank underneath the cab. The 54 may also? I understand what you mean about the holes being different if the tank wasn't there. However, both of the previous posters have a 56 and they say there is holes where the brackets mount.
As for the 48 seat. The frame on it is made of wood. There are no brackets attached. Not sure how it was mounted in a 48. The seat is too narrow also. I have a gap of about 8-10 inches on both sides between the edge of the seat and door. I'm driving the truck sitting on with on cheek hanging off and one on. If you know what I mean. The 48 seat won't work at all.

 

Here are some photos of a 56 seat track (passenger side) that has not been modified as far as I know.
Looking in the passenger door:


Inside the cab, under the seat looking outward: (that's my leg in the background )


The rear inside bolt, camera held behind the "metal plates that stick up"


Hope this helps,

F250Rob- Thanks for the great photos. I figured it out. The seat and tracks I got are from a 54 Effie. I noticed in the last photo, your tracks have a taper going to the rear mounting holes (the part that mounts under the gas tank). My mounts from the 54 are square, no taper. Which I guess means the 54 may not come with a gas tank behind the seat. The rest of the track and bench seat mount are identical. I also see why the metal plates stick up on the floor. I'm not sure if someone cut that taper on yours or if the 56 comes that way versus the 54. It's not a big deal to cut the taper to make them fit. The pictures really came in handy. I guess it goes to show that the 53-54 bench seat is different from the 55-56. Thanks!

The 53 thru 55 had the tank mounted under the cab for some unknow reason in 56 they put the tank in the cab. The only difference in the brackets would be the taper. You are right no big deal to cut the taper.

The only difference the seats that I know of is in the padding 56 is thicker 55 may be also but anyway I had a 54 seat in my other 56 it fit just fine in fact I just seen the truck a while ago sure would like to have that seat back, I'm still looking for a good stock seat.

Mike you are just opposite of what I did. I put a 56 seat in my 54. The seat holes lined up perfectly for the front bolts, but the rear holes were about 1" too far to the inside. So I drilled new holes. I would suggest using grade-8 (7/16") bolts with large 3" backing plates under the floor sheet metal. This is also a good idea for the seat belts so that they don't pull through the floor in a collision. Good luck, John

 

I noticed the 54 seat that I have has less padding on the back rest portion of the seat. I actually think it looks better.
Chuck- You said your fit right in but John says he was 1" off? By the way thanks for the info on the 53-55 seats. I was curious about what year they changed the gas tanks to the interior.
John - Yours was 1" off? Did you have to redrill holes in the floorboard or on the tracks themselves?

 

Mike, I just put the seat in with the front bolts installed and then marked through the back holes of the track. Then I removed the seat and drilled into the marks on the floor. I might have been able to just muscle it in and use the holes that were already there, but I was afraid I might put the seat slider mechanism into a bind. Good luck, John

 

Thanks John. Hey, who the heck is Mike?????? LOL... My name is Ed. LOL....

 

Sorry Mike, er.. Ed, my bad. Nothing personal, I'm just really bad with names. It's a lot easier for me if I just call everybody "Mike." LOL I'll try to do better. John

 

Ed
Well it's been a while sense I did that and I sure don't remember drilling any extra holes but thats not saying I didn't. So lets leave it at the seat was installed in my 56 with very little effort (hows that for trying to weasel out of something).
