Congratulations on getting your Cobra. As for the rest you will find these cars are high maintenance at the best. The 302 is a good motor if it is tuned right and it should run very well. As for the seats, you may be able to find some runners that you can use to mount them on but make sure they don't make the seats to high if you do find some. Since you want the car mainly to drive and have fun, the rest of the stuff you can work on as you get to it. The clutch needs fixing but I don't know much about that type. Good luck and enjoy the car.
