Unfortunately, I believe that doing the conversion requires doing a little more than replacing the motor ( obviously ), I think the actual wiper linkages to the wiper arms themselves are different between the vacuum and electric motors ( different lengths ), so you'll need the internal arms ( inside the cowl ), as well as the wiper arm posts that the arms mount to, to make this conversion work. And, of course you'll need the wiper switch on the dash, the wiring harness for it, etc. Not sure if the car was wired for electric, so you may need to get the 4-wire harness cut out of a Gremlin or Hornet car to fit. I have a '70 Hornet that has ( still ) vacuum wipers, and when I first tried to replace the motor, noticed the arm linkages wouldn't fit on the electric motor! Then found out you have to get the electric ones off a donor car. So, just a heads-up on THAT aspect, if you didn't plan on it, you'll get a surprise when you go to try to install the motor. One OTHER trick you might try, is installing a "vacuum" reservoir on the car, Hot Rodders who are using a "hot" cammed motor have very low vacuum at idle, so will install a small tank to pick up "more" vacuum ( now, how can you have "more" of nothing? LOL ). This allows them to run their vacuum accessories. Might want to try a Speed shop for this setup. But, simply put, a vacuum wiper system is inadequate these days, and it would be nicer to have the electric. I never finished the conversion on my Hornet, as I took it off the road due to needing various expensive suspension repairs at the time. Might have to bring it back online one day. I need another spare car to drive. :) Well, that's my input, good luck on your upgrades, Rebecca. Jerry in Virginia 1 Hornet, 1 Pacer, 8 Gremlins...
