It'* not hard at all it should take you about 30-45 minutes.
All 92', 93', 94', and some 95'* will transfer into a 93' SE.
First, pop your trunk and remove the screws from the plastic plate on the cover and trunk tresh hold. Second, remove the screws from the inside of the rear wheel housing.
Third, remove the lights inside the top of the license plate housing. Fourth, go under the car and pull off the plastic screw fastners from the bumper reinforcement. Five, use a 10mm socket to remove the 3 nut bolts on each side of the quarter panel - just remove the carpet mat and you'll see them.
I happen to have a spare green SE bumper cover in my house, maybe you might want to buy it.
If you have any question email me during buisness hours.
