Any swap meets in your area? Coastal swapmeet in Abbotsford is this weekend May 25th and 26th. You can usually find stuff like that. I know its a long way to travel from PG. Also try the Galaxie Club of Canada
the Canadian site. I can also give you the presidents email, he's pretty good at sending circulars out to the guys. There is stuff out there, its just trying to find it.
Any T-bird or Mercury 390's will do same job, doesn't have to be motor from same year.
