The chrome bezel has little tabs around the back edge that can be carefully
eased out with a flat screwdriver blade just enought to allow the ring to
rotate to open gaps in the flange. This will allow the glass and ring and
sealing ring to be removed. This done you will have access to carefully bend
the needle back where it should be. Then just reinstall glass, ring and
chrome bezel.

They can be rebuilt, but $280.CDN seems very excessive. Expect to pay
$150.CDN or so for a rebuild.
You can possibly get a small credit for turning in the old core. Alfa
