82 280zx bumpers on a 79 280zx?

I have a 79 280zx, and two parts cars, a 79 and an 82. I took both front bumpers off the 79's figuring I could make one good one out of two, but after I took them apart I realized they are both shot. Will the front and rear plastic bumpers off of my 82 fit on to my 79? What modifications would I need to make them work? If not where can I get a front bumper for the 79? THANKS
