I want to put a black billet grill on my 98 stx f150 4x2 but i'm not sure which one to purchase. if anyone knows i'de appreciate it. heres a link to the page http://truckperformance.com/products...LS+%26+INSERTS

 

well i dont think it makes a diff. which one as long as it is black. some say chrome or painted grill piece that goes around it, and then there is a 2wd model. i belive they are all the same. just get the one that matches your description. i would guess since you have the STX that it would be painted and then the 2wd model just to make sure.
