IIRC the first jedi suit to be copied was a skip dive and was not complete. Or if there were 2 arms ans legs they were percieved at the time to be the same..
So while the later TE kits had extra parts suplimented from a tour suit the earlier AP and current AP kit was never changed.
I dont like the extra tour suit parts added later to the TE kits anyway, so with a little work the parts you have will be fine..
