Success with the couplers thanks to the replies!

I worked late into the night to install new springs into FIVE couplers.  All thanks to your help.  Can't say I have the total technique down cold, but I am getting a process together.  I get a great rivet finish thanks to a tool spring loaded punch that I picked up at Northern or Harbor tools.  Now I've got to find the right size pointer nippers so that I can get a clean cut on the rivet head and not nick the paint off of the coupler.  Thanks again.

Now you know why I drive them out with the ice pick...;-)
