Its pretty easy, there are pnp adapter harnesses or you can just wire it yourself.
Although the horizontals are one of the things that let ppl know you are a pushrod 5.0 and are kind of a cool thing to have IMO. I used to get asked when I had my 95 if I was going to swap the lights to 96-98 and answer was always a big "hell no".
My 98 had em tho obviously lol.
Edit: Also the guy with that white Cobra needs a smack for deleting the crabclaw wing off the car. Only car that wing ever came on was the 94/95 Cobra.
