Guys, with the 5" OD aluminum driveshaft I have now, what size do you think I need to make the loop? I was thinking 6" but was wondering if 1/2" is enough clearance on each side during a fishtail moment. Just trying to see what people have done with these large driveshafts since a 2 piece design will be one hell of a fab at this point in time (and fugly with my trucks configuration).
