Help Again Please

Another question for the knowledgeable
I have just finished re-installing the rad after having the rad
re-cored.  To remove the rad I first removed the grill, shroud/surround,
and hood.  Now that the rad is re-installed and all the pieces back in
place I find that the hood is travelling slightly forward and fretting
the paint on the shroud/surround.  My question is, "Why is this
happening and what can I do to prevent the hood from moving forward?"

Thanks all

Toad.
