fix it yourself. It's so easy (did it in my '51) and its $5.00 vs $175+.
1. Unscrew the speedo cable,
2. pull out the guage lights (grab the metal, not the wires,
3. undo the four small nuts holding the guage in the dash (they're tough to reach). They might be finger nuts (round and finger tight) or actual nuts.
4. remove guage
5. the bezel is just bent over the guage (use a screw driver to bend the tabs out.
6. once the bezel is off, careful, glass will fall out.
7. gently pull the needle off
8. do the opposite.
I also replaced the glass since it was out.
Cheers
