There are two car model shops in Yorkville that may have it. Have you checked them out? I can always take a look during my lunch break sometime this week.
(just moved on Yonge north of Davenport)
My friend also orders models online at: www.scale18.com
Pricing is good, online inventory might have it.
Or you could contact by phone or email any of the above places to see if they have it, or can get one in for you.
