03 cat 300 4x4

hi all,
 I'm a newbee to this forum but not to atv's and dirtbikes, anyhow I picked up a basket case (top end removed) 03 300 4x4 for cheap ($200) and need some advise on the front diff and engine. I'll try to be brief .
  1) I understand that the cat doesn't have diff lock from 03 on, I do know that it is a zuk engine ( I own a 02 kingquad 300) reason for buying the cat to rebuild. I also have parts from a 93 ltf250 4x4 entire bottom end, front diff, ect. will the front diff work in the cat? or will it be easier to just rebuild the 250 engine bringing it up to the 300(280) cc specs  and swap it into the cat frame.
 p.o. bought it to flip and lost interest, and noted that the owner before him ran it with no oil. it busted the piston bent the rod and lunched the entire top end so a full rebuild is in order anyway.
 thanks in advance, max

    I don't have the answer you seek but I am interested in what you find out.  I have 5 Cats and one is a 300 an 02 4x4, it does not have the lockable front diff and the 2/4 shifter is on the left not the right side which from my research is the one that can be modified to lock.  If nothing else see if the mounts look similar and check the ratio, in any case your probably gonna have to cab a way to shift it in and out.
