I have an 2003 NFR AP1 and want to go to an AP2 front bumper and lip(maybe same lip as on the CR or an AP2 Lip)
Is it a direct bolt on or if not, what modifications need to be made?
Also, where is the best place to buy a bumper and lip OEM?

Thanks

 

It is a direct bolt on however you will either need to use an AP2 front crash bar or modify the stock AP1 bar (shave the corners)

 

You also need AP2 fender liners, or you'll need to modify your existing ones.

Take a few minutes and search for it, there are several DIY's that walk you through the entire process of what you'll need.
