If it's 281mm total, not center of bolt to bolt, then that's the 10", and so should be fine. The 12" is 300mm total.

 

Right!

 

281mm equals, 11.062992 inches , if that is their measurement end to end the mounting studs would be appropriately 10 inches apart, in that case you're good to go!
Please measure the stud to stud before you install them.

 

this is a catalogue version and the only part that camed out so it should fit, even on local auction portal there are 2 autions that offer oryginal part and they say its 281 (i thought i give it a try). Whats more interesting mecanic measured them and he gived me the 305mm long deatail so i dont know where the 24 mm difference. I measure from end to end.

 

Yours have been replaces at some time with the wrong ones, not uncommon many parts books are incorrect.

 

the best part of this is that the previouse owner replaced the old one 5 months ago but... on our market there are versions that cost ~5$ and are made from metlas + plastic rings on the 12mm heads after he drove 500km those plastic rings on the interior part of those links jus broke in two parts... thats preety strenge for me that this type of part can have a plastic parts thats obvios that phisical strenghts that are pressing on those part will reap the a part if their made from plastic....
