Windshield Wiper HELPPP!

[Dova]

Alright, So I bought a 67 LWB 4wd today. Didn't even think about the windshield wipers working or not till I got going down the road. This wouldn't be a big deal except I live in WA state. Tomorrow I am going to go buy a tester to test to see if I get power to the switch. I've looked through the search engine and couldn't find a lot about swapping the wiper motors to something from a newer model truck. Can someone that knows where a thread is post a link or have some knowledge about it? Thanks in advance. I don't know if it is single speed or double speed. Again thanks. I'll post pictures of the truck in a new thread later.
