Hoods and fenders are not hard to find, the grille on the other hand is not. I have been looking for a spare one for my 2 '78s for awhile. I recommend cutting the rusty floorpans out and fabricating your own back in. It is much easier than trying to put used stock one's back in. Hopefully your motor is good. Pull out all 6 spark plug and squirt in some light oil, and let set awile. Do this if engine has not ran for a long while. Then let set for a few hours and turn by hand, if it does then turn several revolutions--by hand. then change oil and filter(filter is a pain to get to), then try and start. May also try some fresh fuel and fuel stabilizer. I would also prime the carb.
