Another problem is you need the metal sleeve that fits over the bolts and inserts into the triple clamp.If you can salvage those then some M10x60mm bolts with (allen head) will work. aka Automotive bolts.
part No 0012100603 - are you sure is this number is good? because when i put this number in google it always finding 0012100606
I have the sleeve just the screws are crooked, the other parts i still can use, i will repair them with hammer
I don't understand how the aluminum handlebar holder is fine and the metal screws are crooked lel..
Today i called my KTM Dealer and he told me that he can get these bolts after christmas, because now he will not ordered anything and he told me that i can find them by myself in the internet, tomorrow i will go to MR.Bricolage, maybe i will find something smillar to these bolts.
