Rethread to more common thread?

I have some tie rods from an ATV that I need to lengthen. They're M10-1.25, and to get the right threaded rod and coupler is another $20. If they were a more common thread like M10-1.5, M8-1.25, or 3/8 SAE, then I could do it for like $5. The extra $15 isn't a lot of money, but I'm on temporary lay off so I'd rather do extra work, even a lot of extra work so I can save a few bucks. So to adapt this to a more standard thread, what's my best option? Can I just re-tap it at 1.5 pitch easily, or is my best option to drill/tap the female up one size and the grind the male down one size? Or should I just say screw it and weld on standard size adapters?
 
Can you drill out the tie rod end to a larger size like M12, then make a bushing from the M12 to M10-1.25 to thread onto the tie rod?
 
You will have to grind down to the next size as one cannot change the thread pitch. Make adapters maybe, just not really comfortable with messing with steering components. Left hand threads? Hardened steel?

One side is left-hand, I was gonna leave that side alone since it's less common anyway. I don't know if it's hardened, I can't tell by feel and I haven't done any machining to them yet to test. It was off of a cheap Chinese kid's ATV so I doubt it's hardened.

Oops my bad, I guess I didn't read your post as closely as I should of! Sorry about that!

Not a problem, thanks for trying! Any ideas on the best way to go about it? Should I just weld new ends on, or get a close thread and just mash them right together since I'll probably never do anything else with these again?
 
Since you have more time than money right now. You can always make your own threaded rod and / or coupler to exactly what you need. Might be some good single pointing practice.
 
I would not try to weld it, you would not want the steering on a child's ATV to fail.

Not sure what single-pointing is, but I'm using it on a go kart for myself. But still, yeah, don't want the steering to fail. But the whole frame is welded, why would the steering fail before anything else?
