Richard, I have no knowledge of internal condition. It does shift thru all the gears. I got it with my car purchase, previous owner was going to replace the stock 4 speed with it, but never did. looks to have never been apart. I can crate and ship. I know nothing concerning a 215 setup, use in an S2, linkage requirements and or advantages over a 336? I am a Ford Mustang guy so this is a Greek stuff to me.
