i just wanted to know is it possible to put a 92-95 coupe/hatch aftermarket front bumper on a 93 sedan??

Coupes and Hatchs have the same front ends, and sedans and coupes have the same rear bumpers tails. The coupe/hatchbacks have different bumpers, fenders, and corner lamps. The hood and headlights are the same, across the 5th gen body types. If you want to install a coupe/hatch bumper on a 4 door, you will need the coupe/hatchback fenders, bumper, and corner lights. You'll also need to remove the front reinforcement bar, but you'll likly need to do this with abody kit anyways. Keep in mid if you go 1 -piece headlights with this combo you'll need the coupe/hatchback type, as the corner lamps are different (as mentioned above).
