[Boatanchors] Riveting RCA socket in Collins radios

[WW6N]

I am replacing a RF output connector(RCA type) of a Collins KWM2 transceiver.
The connector is attached to chassis by two rivets. I want to rivet an RCA connector 
the same way Collins did. The rivets have no hole at the center.
Could someone tell me what kind of tool I need to do it?  Possibly I want to purchase one
from Ebay.
Thank you in advance.
