There are fixes for this on YouTube. Last week I stupidly dropped a Nikkormat resulting in the same problem on a nice pre-AI 50mm, first time I dropped a camera in over 4 decades. Tiredness, short cuts and a dose of stupidity were the reason. I won't try and fix it and the lens works fine otherwise. I'll put it on my most beaten up Nikon and go for the full combat look.

In Greece there was an unnoticed step on the sidewalk which sent me sprawling face down on top of my Hasselblad 903 SWC. It had the lens hood on which it used to skid away with only abrasions on the bottom of the hood and no damage to the camera and lens. Therefore I recommend that if you are going to face fall do one of the following:
Ironically I'd only recently removed the appropriate Nikon metal hood from that lens. My pratfall was completely my own fault, namely, attempting to lift a plastic box of five heavy metal SLRs with one hand, while balancing two others on the lid. The weight shifted inside and the whole ship went down. It could have been worse, only one camera took a 4 ft drop onto concrete. I feared the worse but apart from said lens thread sacrificing itself for the good of the tribe, damage was non-existent. A testament to the Nikkormat and the stupidity of people old enough to know better.
I have one of these and thankfully have had to use it only twice but both times it was a fairly straightforward remedy with a good outcome.
I do all the repairs I can on my own because I need to keep on working when in the field and a qualified repair person many miles away does me no good at all when I am on the job.
