Nazca Fuego tiller steer stem 1 1/8

[jackventure]

Hello, i'm riding a Nazca Pioneer through Africa since 1 year, my fork broke 3 months ago and i had it replaced with a modified mtb threaded 1 1/8 inches fork from the '90s that i found in Zambia. Yesterday the aluminium tiller steer broke at the welds where it pivots around the stem. Since i want to replace the fork with a threadless one, i am lookingto replace the stem too with a compatible one. I have found on the Nazca website that the Nazca Fuego has the stem that i am looking for, where i could find it? Thank you.
