Right you are, Ken!and 2wd short and 4wd long. 3" diffrence.

I have a set off of my old '83 K30 that would be the same as a K10 longbed, but I'm not sure if they are the same as a shortbed. They will work fine if your using them for a shackle flip, but probably not as a replacement in the front position.
i have two brand new ones, that r stronger then factory ones and yes they r for k10s and k20s check out our web page to see pichures www.indy4x4fab.com
Sorry, I meant K20 and didn't catch the typo. But I think the K10 shortbed did use a different spring hanger up front that was more like the K5.
