gearbox

[tommy1]

hi
im hoping someone here can help
im looking for a replacement gearbox for my berlingo 2006 van,the gearbox code is 20dm47 ,i have found 1 on ebay(same code 20dm47) but looking at the picture of it the starter motor seems to be located at the rear and mine is locate at the front,is it common practise to change the bellhousing from another box or is it just a different box
thanks tom
