horrific wiper noise 2003 tundra access cab

hello developed terrible noise in wiper transmission on my 2003 tundra. disassembled & found drivers side pivot almost frozen, pass side a little better. i found a vid online dealing with this problem on line, but cannot find it again. the fellow in the vid sourced replacements from 2 vendors- 1st too short, 2nd ok. i disassembled, lubed & modified the pivots, would like to have backup parts supply just in case. has anyone had any experience with this? rain just stopped, i'm going to go & install assembly will check back later thanks
