i stripped the rears alittle by using half rate tire shops that over torque with the air GUN.i dont like helicoils,sorry.so i just tapped the rears with a 14mm x 1.5 tap and moved on to 14mm bolts.i really like the dimensions chart you listed .i hit the e brake spring before and heard that noise you were taking about.with the horse power on my limited rated 450 hp i didnt want a weak connection on the rear.last thing you ever want is an unstable wheel.thanks for the dimensions.bye
