C Channel Configuration

Can someone diagram the placement of the C Channel on a 1965 Overlander for me as it is related to the subfloor? Does it lie of it's side (C) with the subfloor inserted into it or is it upright (U) with the floor placement under it? Thanks, Dom

SOMEBODY has to know if the subfloor is slid into the C Channel (C-) or bolted under it (U) on a 1965 Overlander. Anyone able to help? Thanks, Dom

The C channel should be on top of the floor facing up.
The bottom of the U is bolted through the floor.
this is the way it was on my 58.

These two verticals are where the inner skins, outer shell & bellypan are all riveted to.

I never got a good close up of my C channel, but here you can see the floor was completely rotted away, but the C was still in place attached to the outer skin.

C Channel Placement

Looks like in 58 and 59 the C Channel is upright and the flooring is attached under it. I would assume it was the same in 1965. If anyone knows for sure, please chime in. A picture would also be great but a verbal answer would help. Also, is there a shorter C Channel in the rear only beneath the complete body C Channel that the flooring does slide into? Thanks, Dom

That's the way it is on my 1970. More of a U channel

Yes. I think we need to scour this forum and change all the C channel references to U.
Oh, and re-educate everybody too:-D

Anyways, if it was sideways like a C you'd only be able to attach either the outer shell or the inner shell, depending on the way the C is facing.

U is a much better description. The bottom of the U is what makes up the spacing between the two walls. Which is about 1.5 inches.
One side of the U is where the belly pan and shell is attached, the other side is where the inner shell is attached.

I hope this helps.

Todd

If you have any area where you have rivets up a seam and along the floor without anything in the way, you could easily drill out a One or two along the floor and a few up the seam and look into the wall and see how it is assembled.

Getting to an area like this might involve removing some sort of install though.

Aluminum pop rivets are cheap and easy.

Just don't drill out the ones around the door. They are buck rivets and need special / expensive tools to install.

Not all "C" channels are the same. In the early 70"s trailers the "C" channel was a space where the plywood floor slipped into and then had a "U" on top of the "C" where the exterior and interior skin riveted to it. It is a single piece extrusion that looks like a "U" built on top of a "C"

I hope this is not considered off topic but I need a suggestion.
I am at the shell off stage of my 64 Safari.
I replaced the U channel with the newer style U/C channel. Yes, lots of cutting was involved as the floor radius is tighter on the old U.
As I remount the shell, do I apply sealer between the channel and the shell?

Anyone know if it would also be oriented as a "U" rather than a "C" on a newer model such as my 05 Classic?
