i bought a craftsman metric tap and die set on ebay 2 weeks ago and it has already come in very handy. i used it to tap and drill holes into a set of aluminum hinge pin braces and then screwed them to the chassis. they are just like the ones you can get on the rampagehopups site but they have been out of stock forever so i just made my own. i was amazed at how well they turned out. the 5mm screws go in very smoothly and perfectly. wish i would have bought one of these sets a long time ago. i used a 1/8" drill bit for the 4mm screws and 5/32" for 5mm screw holes and both worked perfect.

so i thought about tapping the pinion myself but i really want to get the holes straight and all i have for drilling is a cordless dewalt. i do plan to flatten one side of the motor shaft and then put 2 set screws in the pinion cuz it is very long.
