Okay - not the easiest route - but if you are looking for ultra clean and fully functional - check out the VW wiper mod.
You can see details on my
www.mcspeed.com site under the 69 Camaro.
Basically, you get a junk yard 85 or so VW wiper motor. You will need a couple of relays a capacitor and some spare wire to make it go.
I ended up putting a 1981 Corvette column in my car - then converted to a 1996 Caprice wiper/cruise switch and ran it all through the column. That gave me space to put a fuel pressure gauge on the dash panel where the old wiper switch would have gone.
Again ... a bit more work - but it is so clean and smooth.
