Slow wipers

Drove my '69 Sprite to work this morning in the rain (yes, it does rain in
Southern California...sometimes). Been a while since I've driven the car,
and I was somewhat dismayed at how slowly the windshield wipers worked.
Seems I remember them as flipping back and forth with a bit more alacrity.
Are there any lubrication points in the wiper system I should look at? Like
motor, cable, rack and pivots?
