Carina Ii Heater Bulb/ Dial Bulbs

[Rhythmeister]

Evening folks! My old girl just made 230,000 miles on Sat, I'm so proud of her :D I'm getting a bit fed up of having no heater control lights though. I was able to sort out an import Starlet with a replacement bulb for the same problem but is there a secret technique to getting one into the Carina II?

Also, I need to replace the bulb in dash that lets me see my temperature gauge at night, is it hard to do this?

Cheers B)
