Hi Kelsey R., Thank you for sharing this review about the Hood. Based on our records, the Hood is a direct fit for your 1994 Nissan D21. It also shows that you would like to order a different set of parts; hence, the return of the set of Headlight. Aftermarket products can be any part of a vehicle that is not sourced directly from the car's maker. These parts are direct replacement parts, designed to function the same, may not be physically identical to the original, but there are some instances that it even worked better than the OE parts. These items are just copied from the original which definitely have their pros and cons. Thank you.
