Campag chainring bolts

[evanr4]

I am desperately looking for 2 chain ring bolts for a Campag Chorus 11 speed crankset (2010 model). the one bolt is the one that attaches to the crank arm, so longer than the other 4. Part model number is FC-SR100.

 

I have been quoted between R800 and R1200 for a set of 5 bolts.

 

I a hoping someone has some lying around or an old trashed crank.

 

The pic below shows the missing bolts.

 

Thanks

Do these bolts have a different thread to normal chainring bolts?

Not sure, but would like to stick with Campy bolts if possible.
