Looks like the cable/s still attached on that set up.

Buijs (owner of the car from the pic above) still has the original drum-brakes on his 343. i believe he ditched the cables and uses only the hydraulic line as in the Dutch MOT it is stated that the handbrake must work and is able to lock when engaged, it doesn't say that it has to be mechanic, hydraulic or electric etc.
he's converted the stock handbrake unit from his 343 to operate a hydraulic cylinder, it's a fly-off handbrake untill he plugs in a pin, that's when the original ratchet-lock works again.

i don't know how the UK MOT and regulations is stated, but if you are allowed to use a 1-single circuit hydraulic braking system; do it.
eliminate the original mechanic handbrake + cables, see if you want to position the lever's position better for your driving position and mount it. after that you'll need to cut the original braking line that goes from the front to the back, it is near the top of the tunnel and there's only 1 so it's easy to find. you can get couplings to save work, but on 20+ year old lines you have a guarenteed leak with those, so i'd personally avoid them and bend a new one from the front and one from the back. in the cylinder's manual it is stated where the brakeline coming from the master cylinder is attached, as the handbrake has a internal pressure valve it is very important to get this part right.
other than that, it's simply a bit of plug & play and bend the brake lines. preferably drill large holes (2x diam) through the chassis where the lines go to the hydraulic cylinder, position them center and use a kit that goes hard after drying to secure the lines to make sure they don't touch the bodywork
