Obo... mileage maker!!
I'm interested in getting one, but why is the drill bit needed?
Posting a link for explanation is cool because I can imagine the reason might get lengthy. I need to fully understand before I will purchase.
My AUG trans needs to be replaced. I have a 4k now. And i'm going to swap it to 100mm flanges from the AUG. the .71 or .75 would be nice in the 4k
