I ended up with this model and it works perfectly...a perfect fit with all the right clicking points and groves.  Thanks to everyone for your help. https://www.amazon.com/dp/B07846GTMP?ref=ppx_yo2ov_dt_b_fed_asin_title

Good point.  Thanks again for your help.  It has been very beneficial.

Thanks.  That looks perfect.

It did not.  I purchased it used...the only way I could afford an L lens at this time.  I was just wondering what model of ring would work so that I don't buy one only to find that it doesn't fit.  Thanks for your input. 

Correct.  What I need to know is what ring will fit it.  Thanks for your input.
