Adding Pulse (delay or intermittent) wipers is easy to do... Install the pulse equipped switch and the delay module instead of the more expensive switch without the pulse control resistors. Why is the base model switch more expensive? prolly volume... You may not be able to find the AC Delco non-pulse switch at all.

I'd steer clear of the aftermarket turn and column mount wiper switches. These two switches are such a pain in the caboose to change it's not worth installing the super cheap parts and finding out they only last a few weeks or fail instantly. Even the normally top-shelf Standard Ignition brand switches seem to have a lot less than stellar reviews.

Wiper switches
1984-1987 AC Delco D6283D W/O TILT (N33), W PULSE (CD4)
1984-1987 AC Delco D6354A W TILT (N33), W PULSE (CD4)

Turnsignal switch
1984-1987 AC Delco D6262D

Stalk
1984-1987 AC Delco 22510144 W Pulse (CD4), W/O Cruise (K34)
1984-1987 AC Delco 19244690 W Pulse (CD4), W Cruise (K34)

Pulse (delay) module
1984-1987 AC Delco 15598496 Pulse Wiper Module (CD4)

Dorman makes a replacement wiper arm for around $20 that will replace the stripped unit. The base of the original GM wiper arm is made of cheap Zinc alloy. My guess is it was already stripped and re-installed with bubble-gum and sitcky-tape to sell the truck.
