Wiper motor swap

Thanks, 2 or 3 spd?
Sure the part# is 40-370 from Cardone. If you click the link labeled “security check “ in post it will take you to Carid’s web site. They had 5 in stock a couple of days ago. It’s for a b-body, but the cover can be rotated counter clockwise one notch to work on an a-body. Can’t beat the price!
