XJ-DP-WA

So I picked up a 94 Cherokee from a buddy for super cheap, its extremely clean and only has 132k, I like the look of the late 90s xj so I'm thinking about doin a "97-01 conversion" which consists of swapping over the grill,header panel,front and rear bumpers,front quarter panels, trim, mirrors, anyone know of any problems id run into doing this? From what I've heard its pretty straight forward I just wanna make sure theres no hidden suprises, I already have a 85 xj for my wheeler, but I wanna make this one purdy for the street haha
