Someone said thier mechanic did it that way, but like i said the manual shows nothing. In fact, speaking of the manual i always thought my speedmaster's manual was bad, but compared to the Tbird's it's a wealth of knowledge. It's nuts how useless the Tbird service manual is. aside from torque specs i could almost get by with my general mechanical motorcycle knowledge. It's no wonder so many dealer service depts are so incompetent !
