OK, responding to my own message here. I dug a set of Avocet/Omega inner ring bolts out of the parts bin, and they do fit the Stronglight 107 triple. And the circle is 86mm, so you can use a mod 99 ring. Except the model 99 rings have flats to match the shoulders on the 99 arms, so they look a bit odd as a mod 107 inner.
Anyone know if the Stronglight 106, also 144 BCD, was also available as a triple? Anyone have a mod 107 172.5 left arm they would sell or trade for a 170? The reason I ask is that my 107 triple is a 172.5 right arm only. I have a 107 172.5 double I can rob the left off, but then that one becomes an orphan. Meantime, I have an NIP 170 mod 107 left. I would trade this for an NIP 172.5 mod 107 left (fat chance) or for an NOS or even excellent used.
Finally, I've seen on eBay what are claimed to be TA Tevano triple inner rings. Was the Tevano in fact available as a triple? If so, it was probably drilled like mod 107 or Avocet/Ofmega, since the Tevano was also 144 BCD. Any chance the inner ring mounting bolts of Avocet/Ofmega, Stronglight 107 and TA Tevano were all interchangeable?

For those of you not familiar with obscure French bits, the Stronglight 107 was the second generation top-of-the-line Stronglight crank using the Campy 144 BCD circle in the 80's, just about the time Campy abandoned 144 for 135 (and the short-lived 116).
The 107 triple is like a Campy NR triple or an Avocet/Ofmega in that the back of the crankarms are tapped for chainring bolts to attach the inner ring at a circle much smaller than 144 BCD.
Unfortunately, the crankarms came without hardware. Anyone know what type of hardware was used to secure the inner ring? Any possibility Campy or Avocet/Ofmega hardware would work?
