Jason,
I am putting together a 57 2 ton Crewcab LCF. I a putting it on a 2003 GMC w4500HD chassis(isuzu NPR). I am taking the 2003 cab off and putting my body on. I think the front axle from the IH will be too wide. these trucks are quite narrow. If you do a search on my posts you will find some good information. I was even able to bolt the old 6 lug 22.5 wheels on the new chassis.
