Hyosung gt 125 questions [few issues]

[ko5i]

Hi, there
I have few questions about my bike hyosung gt 125 because everything is from 125 except forks, forks are from 250cc, i had many problems with it for example speed o meter didnt match headlight didnt match and everything that was attached to 125 forks didnt match. But the problem now is front brake that doesnt match, brake matches but the caliper mount bracket doesnt, and i dont wanna use homemade stuff as brackets and extend it or whatever because its break safety first so it need to be durable.
My questions :
1. Where can i find just mounting bracket for 250 front brake i think i looked everywhere around google and all i found was whole brake with the bracket and its around 50-90£
2.Where can i find something to make a thread inside old mounting bracket [ i made new holes in bracket from 125 and it fits but i can put nut on other side so i need to make new thread m6/1.25mm as stock holes had.
3. What should i do ? buy new caliper with mounting for 50/90£ [i have working caliper is just a mounting bracket i need ] or do that thread [but how. I tried with some 'tap' drill tool that makes thread but it was too soft and it melted that tool the thread was gone on that tap its for mild steel and aluminium and the bracket is heavy i think its steal hard steal or something.
4. Also another questions what parts also suits hyosung gt 125 ? because i would want to buy red brake and clutch levers and handle bars but i cant find any for this bike i found for kawasaki yamaha honda but not for this bike will parts from other bikes fit mine ? if yes what other bike parts will fit mine one ?
5.What are good website with parts for my motorbike ?

Many Thanks for helping guys !
