Not very its just a case of swapping everything over, you will need the complete servo, master cylinder, bracket, pedals and brake pipes.

Fairly simple, i did it to mine and it's got the brakes from a similar year to yours.
All you will need is the servo complete with the mounting brackets, master cylinder and reservoir, a different brake pedal which has the clevis pin inside the engine bay instead of in the footwell. I moved the brake componsator valve too purely to leave more room and make the brake pipes look neater.
You can either buy or modify your bulkhead bracket to fit the servo to the bulkhead by trimming some off the edge where required.
So basically all you need to do is:
Drain the brake fluid from the old system,
Remove the master cylinder after disconnecting the brake pedal clevis pin
Remove the pivot pin out of the clutch and brake pedals and fit the new brake pedal in.
Remove the plate the master cylinder was stood on and trim the edge where the brake ms was until its flat
Fit the servo to the bulkhead and bolt down
Attack the brake pedal and clutch pedals back up with the clevis pins
Make some brake pipes to fit to the compensator valve
You'll also require a vacuum from the manifold, some will need drilling and are fitted with a banjo bolt or i believe some are already drilled and blanked off depending on which manifold it is. Without the vacuum the servo assistance won't work.
Once all connected bleed the brakes and enjoy

Fit these pipes to make access easier:
MASTER CYLINDER PAIR OF BRAIDED LATE SERVO HOSES
On all later type minis which have the brake servo built into the naster cylinder it is very difficult to work in the engine bay especialy clutch changes because of the extra room taken up by this dual cylinder. By replacing the 2 metal brake pipes from the servo and fitting these 2 strong flexible braided hoses it means you can unbolt the servo and move it around the engine bay without having to dismantle the pipes ever again which in turn meant having to bleed the brakes every time
