I purchased a flex shaft the other day. It was delivered about 6pm last night (Friday). I started to install it today, Saturday 2/25. It did not have the spring in it. Just the flex and the housing. Is this a new thing or was it accidentally left out on my order? Since this is Saturday I can't get ahold of LHR to see if it is safe to use this way, I'm guessing it isn't. It has been about 10 years since I had to replace one.

Thanks for any advise.
