All S-10 spindles meaning all after market manufacturer, or all years of the truck?
I know the first gen s-10 (82- mid 90s) work, I am not aware of any change in the front end thru recent trucks, so they may all work.
Yes, they will all work as well as the dropped control arms. If you get the late model blazer spindles then you will end up with 11" brakes, then use the dropped control arms.
