Flexshaft gear

Hi folks. I was wondering if anyone has the fiber gear (second one
I’ve stripped out over the years) for the reduction foredom
flexshaft. this one says series 980w but I bet they are all the same.
perhaps from a burned out unit laying around. I have many old and
broken foredoms but only this onewith the top gear reduction :))…
Foredom says the part is no longer available. thanks, Johnny
