Well I called Scott Drakes (SD), they say it's one unit with an upper and lower piece, so that to me means two pieces. The tech I talked to confirmed it, also said it wasn't made in the USA, damn..
I called JEGS, the tech said the made in USA on their site is there because that's what they've been told from SD. So I mentioned they may want to look into it, because if I had ordered it thinking it was made in the USA, and it came with a farmed out country tag on it, i'd be upset as I sure they would too. Tech said he'd be looking into it.
Barry from JoDaddy's Garage answered my email, and said he hasn't gotten to the wiper setup yet on the Brooklyn Pony, but did install a wiper system in a 65 he did with a new cowl setup, no issues. I mentioned to him the mods that are needed on the 66, we'll see what becomes of it.
That's all for now.
