Updating fuse box

[FONT="Comic Sa[I]Ok....So I've done a search but haven't found what I'm looking for. How easy/hard is it install an up to date fuse box (blade style as oppose to glass fuses) from a Chevy or Ford or even an import?I ask because where I live it's not many older Chrysler vehicles around....What are some suggestions? I'm trying to stay away from buying a kit if I can....Thanks [/I]ns MS"][/FONT]
