2012 900xp thru bolts engine tranny

I was wondering if anyone else has used m12x1.75x200mm and m12x1.75x260mm bolts for the 2012 900xp thru bolts for the engine & tranny? As I know the stocks are m12x1.5x200mm and m12x1.75x253mm for the stock ones. As anyone knows u can buy factory ones for 35-40 a pop but can get the other for around 10.00 each. can get thru Fastenal
