Please help. Rust is killing my disco

I have just acquired a 1995 top spec D1. But I need to have some welding done.
The inner front arches AND bulkhead have rotten away. Can the bulkhead be repaired????
Patched or replaced??

Posting some pics of how bad the rot is may help with your questions.

Pics please and where are you?

I'm colchester Essex area. I'll try getting some pics ahortly

It's right where the arch meets the bulkhead it's that crease and going about 4 - 5 inches up bulkhead. Worse on offside than near side if that helps? I'll try getting some pics up

Its all patchable mate but youve got get it back to good metal.which is the fun part.them holes could be 6 to 8 inch by time you get good metal. All good fun welding it up tho and you know its solid.

Get yourself a cheap mig welder anx crack on with it.

Dude I'm in halstead and just had to do this repair to mine. I cut it all back to good steel and patched it with steel thicker than stock panels to hold the rot off longer, treated and painted.

So if I cut out big holes back to good metal and simply patch over and mig weld a slightly bigger piece over the cut out holes that will be good to pass MOT. I don't mind a bit of patch up and go for now. But just can't afford right now to be buying entire box sections and replacing entire wheel arches??

Do you want to pop over to mine and I'll show you what I did with mine. I'm at my unit/disco repair hut Sunday all day working on mine.

Where about are you? would like that but I'm working all weekend are you near colchester?

My disco is off the road. Also needs a tyre but if your nearby I could pop over on my motorbike?

Just to look and get an idea on what the hell I'm doing.

No worries I'm in halstead dude about 20 mins or 10 on a bike

Mate I'm in Colchester just done sills and boot on mine, got some sheet steel you can have also

Id do a patch job for mot then you got a year. To do box section when better weather and moneyis there for the box sections.
