will a right hand case off a 99 scrambler 400 4x4 fit on a 2001 scrambler 500 4x4 ??????

I was told I could use late 97 to present explorer/scrambler R/H case is this true?????

If it is the 99 case is only 129.00 and in 2000 it jumps to 230.00?????
(partsland prices)

I am also wondering about the sub assy(front output shaft) ....if it will interchange???

for starters I NEED a R/H case, pinnion gear, and sub assy

Thanks
