Jim,
Definitely buy new clips. Here is a link to some info on replacing them
http://www.nmia.com/~dgnrg/page_30.htm
When I did mine, it was basically:
1. remove fan shroud (two fasteners at top of shroud)
2. remove hoses
3. remove two clips holding radiator
4. lift radiator out
The radiator sits on two rubber pads that can come out. Make sure they are in place when you put the new radiator in.
Hope that helps.
