Most afe welded at raingutter, but lare are bolted. All the ones i've seen have a thick chunk of jute glued to the ceiling that the support presses against
 
LilJohn. Havent got that deep into mine. It does look like the center support is spot-welded to the roof. If not it would be to the supports. I would have to say roof.

Thanks Bob.
 
Lil' John, I took mine out and nothing was spot welded, to the top of roof. Welded at the sides and welded to each other, by way of the cross piece. There was a piece of jute? padding between the support and roof.

When I weld mine back in, I'll use seam sealer or silicone, between the two, so no moisture gets in there.
 
In line with all the roof support talk...what is the preference on insulation up there? Any reason not to use the waterproof/resistant panels from a Home Depot/Lowes type place?
 
Oh definitely avoiding the tar goop. I was more thinking in line with the stuff they have in the panel department that is fire/heat-rated. It looks like giant foam 4'x8' panels, but not squishy like foam. Some has an aluminum-looking covering to it, and another is kinda pink and SUPER dense. Trying to think outside the box a little:)
 
I have an idea for my 'headliner' kind of taking points from your thread Sno bored as well as a couple others...but I kinda want to give it a try before I post it up here if it turns out to be COMPLETELY stupid! :)
 
Here's mine, spray on Lizard Skin. Two products, Sound Dampener and Ceramic Temp. Control. Sound Dampener goes on first, then spray the Ceramic Temp. right on top of it.

When I redid mine I had the same issue, I used a bottle jack a a 2x4 on the corners of the cross members to get it about an1/8 " from touching the roof itself. The sticky stuff that your looking at is called Seam Sealer. This is what the factory used to seal any sheet metal joints that tack welding wasn't an option. Fill the 1/8 void with seam sealer .Tack welding these cross members will pull the roof around as it cools and may cause it to warp or mis shape.You will find this product in various places on your truck such as between the upper and lower front fenders and around pillars to finish of the joint that have been tack welded.The insulation that is used between the roof and head liner is called Juet padding, it was a foul side and a heavy fiber side . I highly recommend this stuff. It keeps the cab cool in the summer and retains heat in winter.You can attach it by using contact adhesive in a old spray gun, spray the roof and the fiber side of the Juet then adhere. Try not to use the arisol cans of adhesive , it works like crap. Don't spray the foil side. The foil side should be down. A lot of folks spray the foil side and when it gets hot from the sun it separates and falls between the headliner. I have some scraps of Juet and have included a pic. It also works good as a floor insulator between the carpet or floor mat but stinks like a wet dog if you flood your cab going through deep water. Good luck.

Lie down in the back of your Pig and put your feet up against the roof. Similar to wrestling a Pig gastank up into position. Take your shoes off first if you don't want footprints on your headliner. Press your feet up against the sag. Hear it pop out, you're done.
Do not be surprised if it pops back down when you hit a bump at speed. Well, you will be surprised because it will make a loud bang/pop sound when it does, loud enough to make you jump.
My roof has been dented in since I parked mine on it's roof many years ago.
Lost the headliner and one of the roof supports at the time, bent up the other one too. Mine ('74) are/were welded in.
Re-installing one or two roof supports is on my to-do list, and there are several candidates at my disposal. I was thinking it might be nice to be able to bolt the new supports to the sides, with slots for the bolts cut in to the roof support mounts, so the supports could be adjusted up or down, depending on what kind of insulation you had glued to your roof. And so you could push the supports up to really support the roof.
 
Sorta stock...I want to use some stock supports, just more of them and bot-in instead of welded.
 
Lil' John,

My center support wasn't fastened to the rear support, either. looks like somebody had a dance on the roof. It doesn't take much, to cut the welds and drop all the supports. I'm going to add a third suppor, with another light, for the cargo area. Somebody posted about doing it, awhile back. Good idea.
 
Ahh, now the fun starts. I used a cheapo Multi Tool, with an angled blade on it, to get most of the glue. Also used some heat, to soften up the glue ( careful ).

You know what I used, Lizard Skin, really like the spray on stuff, works and stays up there.

I use a piece of copper tubing, that I flatened and shaped, so I have handle on the end. ( gets hot )

I'm not sure why Toyota left the center float, but I might tack weld mine, when it goes back up.

Gonzo, says to use seam sealer between the two, I'll probably listen to him or use silicone sealer?

Good luck with the glue, it's by far the " suckyest " job I've done on the pig, so far :)
