I found these recently...the fastback came from a local drugstore and the hardtop from a local Meijer store. The castings are VERY cheap, but since they were Mustangs and only 69 cents, I bought them for the collection. Have you seen these before?

 

Heres the HT

 

that 1966 coupe loks like a Yatming casting. Lucky finds!!

 

Right you are sir, it says Yat Ming on the back, just looked. Good Eye!!
