Yeah, the plastic trim peices have the end bits to hold em in place.
the part numbers are
NF 16B069 A (LH Side)
NF 16B068 A (RH Side)
These cost roughly $17ea.
They will also need to be painted up, but they do include some heavy duty double sided tape to fit them on to the car.....
Im going to give this a go on my car very very soon (I needed to buy a compressor to spray the bits up), as my paint colour is not available in cans !).
What colour is your Faimont ?????
Hopefully if it is a common colour, you can get some cans to spray them up. (Not hard).
Personally, I have seen this conversion completed, and it looks damm good ! (Well worth the trouble).
If alll else fails, Im sure I cn find someone willing to buy them off you.
