Couple of answers mate
MFA's - Pretty rare by all means, look to pay 50-70 quid upwards. hard to find one in working condition.
Guages - I have oil temp, pressure and volts in mine, not sure if thats orig tho.
Brakes. - They are pants, the guy is correct about the servo/mc being on the passenger side, its because the golf was built for lhd and not for us brits :*(
hope that helps

anyway the best options for perfect breaking is
-Mk2 16V Servo (clevis pin needs cutting down slightly)
-Mk2 Golf 16v/G60/Passat 20/22/22.2mm Master Cylinder (you will require teh larger servo, so this upgrade should be done together)
-239mm x-drilled/grooved brakes
-decent pads (mintex/pagid/greenstuff)
-braided hoses
-brake fluid change
-refurb rear shoes etc and adjust handy b cable...
you'll find your braking will be fantastic after that...
further braking upgrades include
- 4 pot calipers
- 256mm or 280mm big brake conversion
- rear disc conversion from a mk2 golf, although i would get mk3/4 anti sieze calipers for safety, and id only convert to rear discs if i fitted oversized discs at the front. it would be wise to change the proportioning valve at the same.
