preordering question for TW shaft...

I know this has been covered, and I searched and got some info but not all, with the TW 1-piece order coming up, I see that the factory 2-piece makes a slight turn to give the gas tank more room. Visualy with the TW it would clear but it's very close, no one had any issues with gas-tank contact right?
Also they are gonna ask me for specs and I know the length is gonna be 67.5 inches with a 3' lift, but does anyone have the numbers for the flange bolt pattern distance?? I would really like to not unbolt my stock shaft 'cause I live in an appartment and whenever I lift my hood for anything the little maintenance bastard in his silly golf cart has something to say... I've already tolled him to f**k off few times...
