Help! T-Nut needed for Modolo brakes on old Bianchi Quattro

Greetings. I was wondering if somebody out there could help out by
selling me a T-nut that I need to restore a Bianchi Quattro. The T-nut
is from the front brakes (which are Modolo Quattro's). The T-nut is a
shaft with threads on the inside and has a cap on the end with a hex
cut in it for torquing. I believe these were standard on Italian bikes
and maybe others from this era (late 80's, early 90's) and are also
found on Fiori's that I know of.
The nut fits into the front forks to hold the brakes in place. The
bolt from the brakes only goes half-way through the forks and is held
in place by the T-nut from the other side.
I've searched all the local bike shops, e-bay, and hardware and
fastener suppliers without any luck.
Has anybody out there got an old set of these brakes or similar
sitting around and be willing to sell me the T-nut??? Anybody have a
source for such a part?? Any help greatly appreciated. Response via
email appreciated. Thanks

Cheers,
Marc
