Subfloor mounting method?

Recommended Posts

Hi guys,

Can someone tell me what hardware I'm missing and how to connect the subfloor?  These have always basically rested in place in my car and were never really connected to anything.  Here's what I have:

Any ideas?

There are flimsy metal brackets that are supposed to hold the raised floor "wood" up off the metal below. Not sure you'll be able to figure out what's going on here, but this is a pic in which you can see the metal brackets:

Here's a decent pic of the front most bracket. Ignore the cargo lid. That was the project where I added the cargo hatch lids to my car:

Here's a relatively decent shot of one of the rearmost supports:

Hope that helps? You got any of those brackety things in your unknown parts pile?

Oh, and you're also missing the two narrower "wood" pieces that fit into the side recessed areas way in the back. And lastly, someone modified your front most piece. Added the speaker holes and it looks like they took some material off the rear edge.

Awesome, thanks for this!  Is there any special hardware I use to mount the floor?  I seem to remember they have some sort of hinge so they can be raised and lowered instead of being screwed into the car, am I wrong?  I do have the side wooden pieces, but didn't add them to the original picture.   Here is what my hatch area looks like:

So it looks like I have the brackets but am missing the mounting hardware?

Oh cool. You're much better off than I thought you were and you have all the flimsy brackets. So for the mounting hardware, it's pretty generic. Going from memory here since I don't have my subfloor installed like that anymore... There are two types of hardware used:

If there is a threaded insert welded to the bracket, they used the ubiquitous silver M6x1.0 hex head bolt with the Phillips indent in the center. In locations where there is NOT a threaded insert, they used a large Phillips head sheet metal screw threaded straight into the bracket sheet metal. Sorry, but I don't remember how many of each.

And yes, there should be a long piano hinge between the two largest pieces. The front portion (right behind the seats) is firmly fastened to the brackets, but the rear portion (over the spare tire) can be lifted up to allow access to the spare. The hinge is the joint between the two. Is your hinge completely missing? I bet it has something to do with the modification that your PO did to the "wood" piece right behind the seats. I don't think I have any pics of what that is supposed to look like, but I think your PO took some material off.

I dug around and turned up a pic that may add a little value. This is the sloped back style false floor so the shape of the "wood" is a little different back by the taillights, but the hinge is still the same.

Not my car, but this is how the hinge works:

Ah gotcha, so there are long black hinges that attach to the ends of each piece of wood and are screwed into the bracket?  It seems that the two wooden pieces don't connect to each other then?  Any idea where I could get that hardware?  I've looked everywhere...

I made a new deck for my car a few years ago. Some pictures and info here might help: 

 

Any decent hardware store should have everything you need to put yours back together.

What a fine example! :cool:

Haha! Is that one yours? 

I'm not nearly Hoover status, but I nab good looking pics now and then just because I think they might be useful in the future.

The two wood pieces do not connect together directly. They have the hinge between them. That's because the front piece is hard screwed down. but you still need to lift the rear section to get to the spare.

You could probably get a piece of piano hinge cheap at one of the big box stores if you don't have the original piece. And that jars some fading brain cells too... There is a third style hardware used to hold the hinge to the metal reinforcing strips on the wood pieces. It's smaller than M6. Whatever the very commonly used size below that. M5x0.75 maybe? Same screw size they use to hold the center console in place, etc.

Forgot to mention... Buy a length of piano hinge longer than you need and hacksaw it to length.

And if the mounting holes don't line up with the holes on the reinforcing strips. drill new holes that line up.

I can add to your Hoover file. I remember the thread from @grantf in 2011. Here's his pictures that might help the OP. There's actually 3 hinges but a long piano hinge would also work. Any how here they are.

Site, Those are excellent pics of the hinge. Shows how good (or not) my memory is!   LOL

Thanks for the reminder!

These are awesome shots, this will be a massive help.  Could you take a couple pics of how the front board is bolted down and what is screwed into the middle brackets?

I always thought the front piece (the one nearer to the driver) opened as well in order to grant access to the two small storage bins where the toolkits were in the 240.  Am I mis-remembering?

I'll get you loaded down with pics when I get home. About an hour?

NippI'ma do a photo dump for now starting from the rear. This car is in a cocoon and of course the battery was dead so I had to get down in there. LOL

I can answer questions when this K4 kicks in.

The 3 hinges are riveted on the foward peice and phillips head screws on the rear section. Those tool bins are not accessible on my raised deck 280 like my 240. You can see them under the board but I had to unscrew the cargo straps to lift the board to photograph them. There's a long piece of chrome trim that holds the carpet down above those bins.

So it looks like I'm missing the metal piece that lines the aft piece of wood in which the hinge attaches itself (and of course the hinges too haha).  How does that chrome piece that sits on top of the carpet mount?  I'm guessing it has screws that go through the carpet but what does it fasten to?

Thanks for covering for me Site. Looks like I've forgotten most of the details! 

There were big Phillips screws involved though. I got that part right. And the small ones holding the hinges in place (on one side).  LOL

Chase, you're in better hands than mine now. Hope you get all the info you're missing.

And (just in case you didn't know what I was talking about), here's a pic highlighting the mods your PO made to that front panel. Someone cut the "wings" off:
