Cab floor/firewall question

Is the cab floor welded to the firewall?

I just noticed that I can move the bottom of the firewall away from the floor.

Everyday I find more and more rust on this hunk o crap.

I would assume that is not normal. I'm sure someone more knowledgeable will chime in

Re: Cab floor/firewall question

there is a pinch weld where the floor pan turns upward to meet the firewall ... it should be spot-welded solid where there is NO movement.

Thanks Shane, that's what I thought.

Re: Cab floor/firewall question

Can this be rewelded with the cab on and engine in place.

Re: Cab floor/firewall question

It could but I would cover the engine/tranny with a blanket and weld from the inside. EBfabman always welds the inside seam in addition to the spot welds shown in my pics.

Is it rotted? any pics?

Re: Cab floor/firewall question

I haven't gotten into it very far. I was looking at how bad my left kick panel is when I noticed it. I try to get some pictures later on this week.

I'm starting to get real discouraged about this truck.

Re: Cab floor/firewall question

If the floor and supports are bad I would really look at the full floor with supports you can buy. Saves alot of headaches trying to piece it together. There are a few pics of it in my build thread.

Re: Cab floor/firewall question

My only problem with that is I have no way to remove the cab.

sure you do... a twelve pack of beer and three buddies.

or rig an engine hoist, or hand it from the garage or a tree...

take the doors off and the seat out and you only have a 300lb brick then.
