My TB bolts came out pretty easily and the 'O' ring was all wormed up like George's was (came out in a couple parts too). Cleaning was important, and torquing was easy when going back together. I kept reminding myself the parts were real soft metal and to not over torque. Only have to squish the 'O' ring for the most part. I just might go back in there with the torque wrench someday soon to see if those TB bolts came loose any.
