My '66 had them---They Don't!!!! Ya haven't lived until hammering it in a snowstorm (or rain) and having to let off the throttle to see.... Best thing I ever did was to upgrade to later model electrics with delay....

If you have vac wipers and a v8. You should have a bizarre looking fuel pump with vac ports on top of pump. I do not see anyone selling these yet, but if you need one letme know. X2 on electric being a better option
