1982 bumpers on a 1979 280zx ?

I have a 1979 280zx, and two parts cars, a 79 and an 82. I took both 79 bumpers off figuring I could make one good one out of the two, but after taking them apart, I found out they are both shot. My 82 parts car has the all plastic bumpers front and rear. Would I be able to use these bumpers on my 79? What modifications would be needed? If not, does anyone know where I could get a front bumper for the 79? THANKS
