Old Merc Spark Plug Wires

Hello everyone,
I've got an old 70 Merc 800, that I want to replaced the old plug wires on. I got the Sierra plug wire kit for this motor.
Now my problem is the terminal ends that screw into the cap. HOW do I crimp these things to the new wires? It's driving me crazy. The brass is too brittle and snaps if I crimp to far, but when it doesn't break, they don't hold the wire tight enough and slip back out.
Can I just buy premade ones? Probably not.
If not, has anyone made their own replacement wires, and what crimper did you use, or just special trick?
 
You can buy new screw in ends for the wires, I soldered my in after stripping 1/2" from the wire, putting some solder in the terminal and applying heat to melt it. Ready-mades are available from online.
