Helicoil help (shift knob swap)

[MrFairlady]

If someone could please point me in the direction (website showing the Insert i need) of finding a helicoil for a Shift knob I would like to use.
The knob is a Toyota pitch M12x1.25 , going on a Nissan Shifter (M10x1.25)

I Need to purchase a Hollow Threaded insert i guess,to thread into the Knob to allow it to then, thread on the Shifter.
No I don't want to ghetto it up and use tape. That Didn't work nor Cut and weld a bolt. Surely this is avail?

I tried the helicoil Website and It is impossible to find what I need/part number and then where to order it and did not want to order the Wrong 1.

A little help please for those that have purchased these.

nice, thats cheap!
auto parts stores sometimes have these (oreilly, pep boys)
but they come in a lil set, for about $10 or so.
def not as inexpensive as TF has it
