That is the one for the light duty small block bottom of the line bolt in radiators. It is correct for 69 but will work for 1967-68. Won't work for the clamp in radiators or any big block applications.
I came across (finally, don't know why I hadn't checked them out before), Mustangs Unlimited .Com and have actually already ordered some parts from them. 69SCODE -- Try them, I found my shroud for $90 http://www.mustangsunlimited.com
Speaking of fan shroud's, I was checking on my car at the paint shop Thursday, Starting to clean up the engine compartment and one of the painter's thought he would do me a favor and paint my nos big block shroud for me......:angryfi: need I say more.
