I am a newbie to this forum but I am very active in many other forums, I have a 89 K-5 and a 79 K-5. I know all 80's years front clips are interchangeable, My friend just told me, to put the clip from the 89 on my 79 i would have to lengthen the frame...... Is this true or is it a direct Bolt On. He said the older fenders are shorter. The 79 I got has 4k original miles on it, but is a bit beat up due to being used to plow a lot its whole life. However it was kept indoors. Thanks in advance for any input.
