Paint and Body Aero to 4 eye Front End Swap

Hey Guys, I am currently building a 1988 Foxbody Coupe. Had the aero front end but I decided I liked the 4 eye look a lot more. I know what main pieces I need, my only question is, what do I do about the front bumper cover molding not matching the rest? Do I just sand it/fill it in so that it is smooth? I know the alternative is getting a rear bumper and bumper cover and getting the molding that matches that period.

Any help would be appreciated!

Reason I am not just selling the car and buying a 85-86 4 eye is I sunk a lot of money in fuel system and engine that I cannot get back.

I’ve already read this thread, the link they posted doesn’t work. No one speaks on the molding. Then they just start bickering about the swap.
