Odometer retaining clip for 1958 Ranchero

I broke the little spring clip that holds the odometer in its cradle, and I don't know where to find a new one. The speedometer in my 1958 Ranchero quit working so I'm installing a used one. I tried to transfer the odometer, but broke the retaining clip. Please help. Thanks.

 

Another speedo and a visit to a speedo repair shop are your only places for that.

 

That clip should be the same for a 59 and I have dozens. pm me
