The back plates will probably be the only thing left on the car.
Sample pics:


The car will be used lightly in moderate>heavy city traffic, no hilly surroundings except occasionally.
Would you be so kind to try and sort out/fill in/enhance/comment my options?
Option 1 as I see it:
I imagine I will have to buy a replacement kit (all hardware incl M/C and all/most of the piping).
Are these 1960 brakes 7" or 8" par default? I forgot to measure them while in the garage

Advantage: simple, quick work. Bolt-on, bleed and forget (for a while).
Minus: weak brakes while driving, constant worries at the Swedish MOT about uneven brakes
Who sells a complete 7" (or 8") kit? Experiences with the kit?
Option 2:
Install larger drums if these are 7"
Advantage: better brakes, almost as quick/simple (?), bleed & forget (for a while).
Minus: non-original parts on car, where to get 8" spares in the future, almost equally shoddy braking and same MOT worries.
Who sells size conversion kits? Experiences?
Option 3:
Fitting a disc system in front, keeping rear drums.
Advantage: better brakes still, even without servo. Semi-bleed & forget, only rear drums to worry about at MOT, apart from normal (easy) service of front.
Minus: probably expensive, not so easy to install, hard to find spares if "donor" is exotic (this is Sweden).
Who sells front disc kits? Experiences? (I read some about this in another thread, but it went OT quite quickly....)
All pointers and suggestions welcome.
