I have a 2005 Millenium Tempest with a bent King Pin. It's 7/16 - 20 NF. I contacted Millenium Chassis for a spindle and I was told they do not support that old of a chassis. Tried searching for a bolt long enough to have the NON-threaded part just short of coming through the upper heim joint and cut the bolt thread down long enough for the nut, washer and the cotter pin. I was not successful in finding one. Can anyone suggest a replacement. Thanks.
