Can I do this by simply changing out the front cross member? I believe the frame on a 4wd is arched more or something.

whole front suspension has to be changed out basicly but yes it can be done

Is the frame not different?

It would litterally be easier to swap your frame to a 2wd frame.

I am looking at buying the crew cab project off 72supercheyenne. The frame he has is a 4wd. I have a 2wd parts truck that I can take everything off of. I believe these frames are different and do not know if it's possible to use the 2wd cross member and a arms in place of the 4wd stuff.

Thats the crew thats already disassembled and shortened correct?

Yes, that is correct. I don't suppose it matters. I have a welder and if it's different I dan cut the frame off and put the 2wd section in it.

Thats a little different, I thought your OP was about a complete truck. Should be relatively easy then, but youll need more than just the front cross member.
