so a friend got a couple bikes for free a while back and we were going to rebuild them. i decided to start with this one but i am curious about what year it may be. heres all i know. 1) its a nishiki 2) it used to be red ... and thats about all i know but heres a pic, hopefully it'll help.
Yep - bent front forks. Does the seat tube and down tube look to be 'creased' near the short, front head tube? If so - throw the frame away. It could be fixed but this would be very expensive and it is difficult to find someone with those skills. If the frame's not bent - change the forks but you must replace your fork with a fork with the same size steerer tube and take the correct size wheel (probably 700C) which is reasonably easy to find.
I would say that the frame was a 1970's frame (clamp on front derailleur, one set of bottle mounts, cable guides brazed to the top tube, plenty of space between the rear wheel and seat tube).
