[T3] Speedo Repair Suggestions?

[Doug Brashear]

Hello all,

Though the speedo needle responds my '73 Fasty's odometer and trip meter only work intermittently. I bet it's just that the aluminum gear wheel has loosened on the shaft...but having dealt with the repair on a bus speedo only to have it start acting up again I'm looking to have the proper fix done. 

Anyone have any suggestions for speedo repair shops that might have VW experience?

Thanks!
- Doug :-)
