Rusted chassis

[shazc]

Hi all, I have just bought a viscount valiant alumvan, 68 model I think. The chassis seems to largely have surface rust but there are a couple of spots on either side near the back corners that are more serious. Is it possible to repair the chassis without removing the body of the van?
Please see attached pics.

Hi Shazc,
This appears to be serious decay.
I would be seeking advice from an engineer or steel expert, this is what you can see, what about what you cant see?
Others here will have more experience, I would think removing a Viscount body from the chassis would be an enormous job?
Get advice.
