What will be the difference using the later axle? Truck is 1972, axle swapped in at some point in the past.

Will the plates that come with the IHPA kit work on the 74-75 disk axle?Your question does not have much context, so I am not sure how well I can answer your question.
Sounds like your axle was swapped in at some point? An IH axle only uses three ubolts on the front axle. Either you have a 74/75 axle if it has external locking hubs or a Chevy axle. The suspension kit doesn't care what axle you have, as long as you get the correct ubolts and plates to make it work.
