If they are like the AD of 47-54...yes, I know there were major changes...the cab areas all interchange, but not the front clip....I have two front clips of the 4000 and 6000 that I use as patch panels. Nothing fits...every thing is bigger, longer, wider, etc. Many people sell those parts saying yea they fit, but they just want to get rid of them! So, bottom line...measure ten times before you buy. rod
