Does anybody have handy a photo of the rear cab mounts, from both the topside and the bottom? I am pretty sure they used to be where the floor of my truck was cut out, but I'm not positive. I may move them anyway, but it'd be nice to know.

Dave

 

What year truck are you working on?

 

Sorry. Forgot that this wasn't in my build thread. The cab is a '47.

Dave

 

I think I may have found where the holes used to be. They were welded in. But I would still like to get confirmation of the location. I'll take some pics tomorrow when it's light out.

On the rear cab mounts underneath there is a piece of channel spot welded across underneath of the cab that reinforce the sheetmetal of the floor. A wood block fits accross this channel on top of each frame rail and a bolt passes though the frame and each block with a couple of springs underneath, I think its for flexing of the frame. Inside the cab above the channel in the rear there is a couple of metal plates welded to a raised piece about 1 1/2 by 3 or 4 inches I don't know exactly, that reinforce the area where the bolt passes though. This is probably way more than you asked for. I just finished repairing that area on my 46 and I couldn't help myself

 

Thanks for the information! Here is what I have...

This is a shot from the top of the floor in the rear corner. You can just make out a spot where a hole was welded in. I believe this is where the rear cab mounting bolt went.


It's more visible on the bottom. This photo is from the center of the cab facing outward.


As my cab is mutilated, can you tell me how far over the brace/bracket under the floor extends toward the middle of the cab? I can tell the 1 3/4" wide brace goes all the way across, but the shorter one that goes all the way to the corner appears to stop somewhere in the middle of that big void.


Here is what appears to be another mounting bolt hole, but it has a plug in it that appears to have been there for awhile. Is that normal? Would there normally have been a bolt there? I believe this is the bolt that I have seen in some of the gallery photos, but I'm not sure.

My cab is still laying on its side where I'm finishing the welding, so I can still maybe give you some measurments. The Channel that extends across the back is 49 1/2 inches long give or take a 16th inch. The corner pieces are under each end of the channel as you can see. They only extend 1" past the center of the mount hole on each side so they aren't very long.
Picture #1: The mount hole on mine is 9" toward the center measuring inside the cab from that plate sticking up behind the seat riser bracket shown in the picture
Picture #2: Its hard to tell exactly but I don't think this is a mounting hole. put your tape against the inside lip of the corner plate, the mounting hole is 9-1/2 inches inboard give or take a 16th inch.
Picture #3: Catch the end of the channel with your tape and measure toward the center, the mounting hole is 9" to the center of the hole
Picture #4: This is not a mounting hole. I don't know what its for but it has a plug in it. I think its a locater hole used in mfg.
Picture #5: This is not a mounting hole also because it also has a plug in it. Measure from the inside edge of this plate. The hole is 1" to the center of the mounting hole. There is a block of wood that fits crossway inside this plate. There is no cross channel brace here.
Hope this gives you an idea. I wish I could take a picture for you but I have no way to get it on the computer. I don't have a digital camera

 

Thanks! I measured all of the locations the other night, but I didn't write them down. I'll have to go re-measure. The (filled-in) hole in the first 2 photos is the same hole - one from the top and one from the bottom. The same goes for the last 2. I'll try to get back out to the garage after the kids go to bed.

Dave

 

Made it back out to the garage. The holes in the pics are spaced 41.5" apart, across the cab. If the cab mounting holes were 9" from the edge, it would have been in the area that is cut out. Thanks for that information. I have a better idea now, what Ford used for mounting, so I can make sure I have at least as good a system.

Thanks again!

Dave

 

Dave, You may already know about this place, but you can purchase good quality floors and pieces for these cabs from here: http://www.northernclassictrucks.com/ . This is where I got mine.

 

Thanks for the link. I've been to that site a few times and they do seem to have just about everything I might want, except that I'm going to be modifying the floor and doors and A-pillars, and .... So, rather than buy a new part and cut it up, I'm just going to form all the pieces from scratch. It'll be good practice for when I start forming the fenders and hood. (And aside from some elbow grease, it'll be about $1000 cheaper!)

Dave

 

Well, I think I am going to try to use the Ford mounting locations for the cab. The front mounts will have to be moved inward as I am going to need that spot for suspension clearance, but the rear shouldn't be a problem. In fact, I don't think it will be all that difficult to make replacement brackets. We'll see if I eat those words.

Dave

 

Hey Guys.. I threw up some cab mount pictures. The link is as follows:

I hope this helps you, as I just went through the same aggrevation remounting my body.

John

 

Thanks a million for that page!!! It sure fills in a lot of blanks for me. Interestingly, all 4 rear mounts have been cut out on this cab. The ones at the bottom of the toeboards are rusted through apparently, which explains why I didn't recognize them as mounting locations, though it does make sense.

Here's the right toeboard location.


But, this hole does not appear to have been welded in, and yet there is no hole in the floor pan. I can see a hole in the brace underneath, but, unless I'm mistaken, there was never a hole here. I'll have to re-check this tomorrow afternoon, I guess.


BTW, what kind of frame is that? I had kinda guessed that the cab originally bolted right through the frame rail, but the forward mount is bolted to a bracket on the side of your frame. Is that the way that Henry did it, or is this a mod?
Dave

 

That is Factory (I believe as the tabs were riveted). The rear and center mounts bolt through the frame. The front mount has frame tabs for both the front and back bolt. If you measure the distance between the front cab mount rails (below firewall right and left), you will see that their centerline width is about 2.5" wider than the frame centerline width at this point. I know that there are some subtle differences between the 6 cyl and v8, but I think the frames and most of the body except maybe the radiator top shroud, were universal.

P.S. Ford used a rivet to hold the center and rear mounts to the cab about an inch away from the mounting hole so that the mounts didn't move or dislodge during setting of the cab. On the web link ( www.computerliterates.com/47Ford ) the photos of the original pieces show the remains of the rivets.
