1998 A4 front end vs 1997 A6 front end
 

Hello all, I have a 1998 A4 that needs a hood, fender, headlight, bumper cover. I found a good condition front end on a 1997 A6. I believe they are a little diffent, but could I put the complete A6 front end on it, with little to no modifications needed?
Thanks for any help.
