Not really anything else to change, local rad place will most likely be cheapest though shop around as my quotes ranged from £38 to £93.
A tip I would give is to drill out the two rivetts that hold the bracket that secures the bottom of the dash in front of the gear lever, heater box then pulls straight back and out, just use metal screws to secure bracket back down.
Make sure the cables are adjusted properly.
