Put together from NOS Polaris parts from Polaris packages, all but the bolt & nut. According to the book, they fit the 78 & 79 TXL, & 79 Centurion. Kit contains thick spindle 1821020, top & bottom bushings 3573908, pivot bushing 5010059, bolt 7515417, and lock nut 7542403. 

Theses spindles are almost the same as the 1821010 spindle but the shank is thicker. They have surface rust, but are NOS. Nicest ones go first.

This should restore one side of your machine.

Please make sure these are correct for your machine before you order. Thank you!
