i just did mine and it seems to bolt right up as fare as i can tell! as long as you have all the grills and lights from the new bumper. im not done with mine yet cause im waiting on my front mount but i took the old one out and just shoved the new one in its place for now. it slid right in! i did the same thing to my old supra and i dont remember moding anything! i think its the rear tail lights you have to drill a couple of holes to go from older to new!
