Has anyone seen something like this before? It's the driver's side front rail, and the only one that looks like this. I want to put subframe connectors on, but now it looks like I have to take care of this first. You think a curb did this, or possibly something else?

Well, what you are doing will destroy one. It is NOT a jacking point. If floorpans are weak, that rail will go straight through the floor.

I would put a straight edge ont he flange that mounts to the floorpans to check and see if it straight. From the picture it looks really bowed, you might have to do some floorpan surgery to fix that mess.

I see.
'67's must be different from '69's.
I've had a couple of 69's (base sportsroof and a Mach) since 1980 and I have never had a problem jacking them up from the frame rails.

You need to place the jack farther forward, not on the floorpan extension.

That is NOT a frame rail, it is the floor support and it is not a good place to jack at.

So here is a question... say you've got a frame rail that messed up like that... or maybe even less. If you were planning to use through the floor/frame subframe connectors; could you start them forward near their beginning point and basically cut out the bottom off the original frame so the connector acts as the bottom with the sides of the rails welded to it? This way it directly ties in all of the subframe?

You can do that, It is kinda like what I did however you going to have to angle the subframe connectors to attach to the rear subframes. Also the rear subframes are about half the thickness as the front. Your better off tieing in the front to the rear spring mount. Just my opinion.,

That looks exactly like my '66 does, and one of the PO's had a front end D/S accident right at the fender. I'm not looking forward to replacing that either.
