Like 1200RC wrote, if you let us know what country you are in we can steer you in the right direction better.

The brakes on the 1200GX are the same as any 1200 coupe. This is a fairly straightfoward job & invloves you sourcing a set of 1200 coupe front struts, complete with brakes, & a pair of rear wheel cylinders, also from a coupe. New ones are cheap enough & are tour best bet.
This would be a really good time to overhaul the master cylinder & if this is done, then removing the residual pressure check valve for the front brake circuit will convert it to a disc brake model. Again, new master cylinders are not too expensive & a new disc brake master cylinder is also a good choice.

Just update your location & you'll be on your way.
Oh yeah, welcome to the club from all in Australia.
