Factory 69 Cuda Tach needle came off - easy reinstall?

[cgfen]

Hi.
While sorting out an oil gauge issue, we
took the time to "'refinish" the dash surround.

• sanded the "chrome" areas
• replaced the woodgrain with new aftermarket
• sprayed new Duplicolor chrome paint

It looks much better than before.
Also painted the gauge needles neon orange, tach needle came off during this process, but I think I got it back in place.

Maybe not.
all is reinstalled, tach seems wired correctly, but no needle deflection during engine run.
When I reinstalled the needle it seems to press in place with no issue.
The mounting pin on the needle seemed to pass through a small gasket / o ring during insertion.

Have you ever done this?
Any ideas on what I may have missed?

Thank you

Craig

Never mind.
Got lucky
Found that the 12VDC lead to the tach had come off at the fusebox end.
all is good.
