Hi, I remember my mk2 and had the dials out many times (1st for paintin them silver.... then coz the needles except the speedo???...stopped working)
Anyway..
1,Remove the surround (two crosshead screws at the top)
2. unscrew the instrument panel (2 screws, 1 each side)
3. It will then rock forwards, just take it off the supports, push it back, and squeeze it out the top of the steering wheel over the horn (mine didnt have an airbag though
4.Search for screws that fell behind dash...
5. swear a lot, and admire grazed forearm...
