frustration!

I recently got a good deal on a DA 10 pitch crankset and BB online. they were in great condition, and I was really excited to use them. From what I could find online, I was under the impression that they were 122 BCD; an odd size, but still available in 3/32 pitch in the form of stronglight (french) chainrings. So I found a deal on a stronglight chainring in 122 BCD and a size that would work for me.

It arrived in the mail today, and thats where the frustration really begins. Turns out that the DA 10 pitch cranks are NOT actually 122 BCD, but something more like 123-125...no luck finding anything in that size yet.

So I guess my question is this; does anyone know FOR SURE what the bolt pattern is for 10-pitch?

Otherwise, it looks like this stuff will have to be for sale (or trade) soon, to fund the acquisition of a new set of cranks.

Any info, tips...****, anything at all would be very helpful. Having track bike withdrawls riding my conversion all the time.
