I have never tried coronet headlight mounts the spacing could be different & the depth could be wrong although the depth should be an easy fix
dropping the T bars & re-aligning the tires hsould get you close , using a lower profile tire will lower the car as well
you may need to make custom mounts for the SRT seats , also the floor pan will be different between the two so you wil have to modify the mounts , I have never tried to fit these yet so they may not physically fit I don`t know , wiring is no issue , you will need to access the Red 3 prong Tri plug under the dash & route wiring under the carpet to run the adjusters in the seats
