For the bones w/blades here's what you can do.
1. Get a set of IRS pin cushions and some schumacher blades
2. Cut each of the pin cushions plastic bits in half
3. Install the pin with the half bit of plastic in each drive shaft (add a drop of CA to make sure it stays put)
4. Put the schumacher blade on and re-install on the car
It's not difficult to do though the pins have a tendency to slide out a bit if you don't CA them in.
