Inside Tunnel Rust Options

[DennisO]

Hi All,

I finally had time to get back to my '75 project after life kept getting in the way :-) I have about 95% of the car disassembled and have a pretty good idea of all the rust and hidden damage. The floor pans have some surface rust and a couple of spots that might need a patch (eg by brake/clutch pedals). However, the floor inside the tunnel has some pretty good rust that must be dealt with. Odd, but it look like water leaked just inside the tunnel and sat.

Is there a good way to remove the tunnel to access the floor underneath? This is probably not a good idea, but can the floor be cut on both sides of the tunnel, removed, cleaned, painted, and rewelded? Any other ideas?

Thanks,
Dennis

Guys,

Thanks for all the great advice.

All the cables (clutch, e-brake, heater) have been removed. The harness and battery cable have already been removed, and I'm going to remove the fuel lines, since I plan to replace,

I do have a couple of questions regarding the 50/50 solution of ospho. is there any concern about ospho getting into the joints (eg tunnel and floor spot welded joint) and cause me problems down the road? Or does the repeated rinses get it all out? Is it OK to you a propane torch to lightly dry the area in addition to the forced air?

Thanks,
Dennis
