I can get the whole front end w/ lights, fenders etc.. but i was told that i either have to buy a jdm radiator support or modify my current one. This true? How would i modify it? What else would i need to do?

 

I am not being mean or anything, but this topic has been beaten to DEATH on this forum.
Now that the archives are working again, use the search button, type JDM front end, pick the CRX-EF forum and select archived topics.
I came up with two pages worth of JDM front end related stuff.

 

to save you very little time, you can use your rad support, and the rest just bolts on
