intermittent wipers/pump question
 

For my 76 Chev, I would like to upgrade my wiper situation from 2spd to intermittent. Is it only the switch replacement? And what year can this be found from.

As well as is there something I can do to stop my wiper fluid from 'pulsing' and drowing my windshield with fluid five times after its already clean? A switch for the pump that only gives fluid when I hold it would be nice.

Thanks boys. and girls (?)

I believe there is a little more invovled then just changing the switch.I think there is also something that goes on the wiper motor but i,m not sure.As far as the washer you can put an aftermarket one on that only sparays while you have the buton pushed
