I have a 67 and converted to electric wipers after using the "individual boat wiper motors" for awhile. The hole spacing in the windshield frame is likely different than BOB's 74 (yours will be about 4" further apart). But, BOB's linkage can be modified easily to work. Basically you cut the longest arm and extend it. There is a really great thread on the national bronco site that covers this. https://classicbroncos.com/forums/showt ... p?t=293394
Here's a picture of what I did. There are a couple others in the group who have done the same thing.
Best of luck.
