crazy upgrade, did it myself and i love it.
Here is my proof as to how much more power the newer motors have..
my windshield wipers got really slow, and eventually started working. so instead of a trip to a junkyard (sadly none near me) I had a friend ship one from NB to ON
I did the swap because mine died, but its a goood upgrade DOO ITT!. I took the old motor out, and low and behold it works fine, the linkage was seized so the old motor wouldn't even move them. New motor in, powers right through it, and one day had a killer rain storm. Wipers on for 4 hours freed it up nicely. Now there super duper quick! Easy upgrade, take out three rivets, drill three holes, crimp one or two wires. Good to go.
