Better he ask here where we have nice guys to help him, then go to a dealership and ask.
I was 16 and went to a local dealer and got laughed at because I didn't know what a Shroud was (for those wondering english also isn't my first language so it's kinda hard when I didn't know words growing up.)
Just so you know if you have a 89+ and now have an pre 89 style bumper and want to switch the center piece you will also need to swap the turn signals and will have to do some modifying to get the pre 89 signals and pre 89 grille to fit. In other words its not a direct replacement.
I prefer the 88>86 front idictors also it seems to be made of different plastic as mine is a jap import and ive noticed that the newer style indictor full JDM orange and Euro version always go a faded look the older model longer indictors always maintain a glossy finsh. ive modded my grilles to fit hehe need bust up a picture
