Range Rover Classic 1988 Weld Repairs

Hi everyone,
I'm a recently new owner to a Range Rover Classic, it is a 1988 3.5 efi.
I purchased this car in March and I've done a few bits to it, new exhaust and injectors, adjusted the flapper unit. Its a great original car with low miles and everything is where it should be, I love how simple this car is to work on, aswell as the robust all metal construction of components, I understand why so many of these cars survive.
Unfortunately a head gasket has gone so I've got to do that soon.
At the moment I'm doing a few patches to common rust areas at the front. I need to do the A pillars ideally but I don't have the workspace to get that involved.
Here are some pictures of the progress.

Just what I've cut out so far

View from inside

Crusty A pillar, going to just beef this up on the inside for now

When you say, beef up, do you mean welding a plate over the rusty area?

Col

Essentially yeah on the inside of the A pillar, I won't be welding onto actual rust though. I would much rather repair using one of those sections you can purchase,I plan to do that in the next few years along with the sills =)

Looks to be fairly good to be honest, what's the rest of the car like?

Can't see the photos, just red crosses.

here is the first patch i've made

really struggling to get photos to inlay with the message, hi rallymantoney, the rest of the car is quite good i think. there are parts that will need addressing though, 2 body mounts look bad, one of the light boxes has gone, i cant see anything else that concerns me. its original asides from several dodgy patches. mostly in the footwells and floor.
