Looks like the hole for the wiper switch was cut out by hand vs. factory plus the extra screw to the top/left of it that doesn't belong there.....I googled 1985 Buick Regal and then clicked Images.
Took about 30 seconds to go.. "well, it looks like someone got themselves a totalled buick and put the interior inside an El Cam.. Seats.. Dash.. then charged a little more for it.
Interesting find! Did you buy it?
