You will likely have a hard time finding the conversion kit. HOWEVER, luckily for you, Savage is in Ontario and you can order all the parts from them. As you likely already know, the Savage 64 shares the same parts as the Cooey. This is what you need to do....contact Savage at the following number
Savage Arms Canada Inc
248 Water St PO Box 1240,
Lakefield ON,
K0L 2H0
705-652-8000
Below is the list of what you need. The part numbers should be correct, but tell them what you are trying to do and confirm the following
2 of 700426 magazine housing screw
2 of 700456 lock washer
1 of 700484 magazine housing
1 of 700485 magazine
Let me know what Savage says. If the cost seems a bit high, I have and may decide to part with the parts you require to convert your gun.
Hope this helps.
