Has anyone upgraded their wiper motor

[BLOWN73]

i put a column in my 73 blazer out of a 90 burb it think, and i took the wiper motor, to make it work you also need the delay box that plugs into the column, looks like a mini amp, the wiper motor bolts right in with the expection of the little part that attaches the motor to the wiper arms, so back to the junl yard where if i remeber right a late 70's has the old style wiper arm with the new style mount to go to the motor. but the crapy part, i never wired it in!!!!!!!!!!!1
