this MA45 diff wont bolt in to your sprinter you will have to get the suspension and panhard mounts cut and moved or swapped over from your existing diff
this will add to your cost by about $500 - 600
the trouble and cost of putting this ma45 diff in u may as well find a jap spec AE68 diff, or upgrade to a F or G series.
the ma45 diff really is only worth bolting into an RA40 when you weigh up your options
