I havent seen this asked before and i was mondering. how do you drill and tap a 203 for the round 6 bolt pattern? i know how to drill and tap so thats not what i am asking for how do you know how much rotation to put on? Im planning a 700r4/203/205. ive rounded up the 203 and already have a 700r4 w/ 208 adapter and a clocking ring. i can use the clocking ring as a templet right? now its just a metter of getting that ring into the right place. also can i go to deep with the holes or does it not matter?
