i recently bought some drop outs without realising the thread was 1.0 fine, but the maxle i intended to use is 1.75, so does anyone know where i can source an m12 x 1.0 ( 217 long). i have searched for ages on google, so im not being lazy.
dt swiss x-12 would be ok, but the bolt is too short at 142
i reckon if i tap out the 1.0 drop out that there wont be enough aluminium left to make 1.75 thread. so my options are i think:

Find the correct bolt
Make a bigger hole and helicoil the drop out
Use a slightly smaller bolt and but a nut on the end
Weld the much shorter m12 x 1.0 that i can find, into one longer one

any other suggestions 🙂
