stump,

OK, I'll buy that explanation. I don't have that part so I wasn't sure.
Get the MicroHeli lower head, it's all one piece. Mine has worked great so far...only a few flights.
And it is lighter than E-flite's.

HopMeUp on ebay has the part for about $9 plus shipping. It comes in blue or silver. I've had excellent results with this seller.
I also have their phone number if you want to call them about shipping to Canada, PM me.

You could always use something like JB Weld to stick them together.
