Tripod ring mount needed for EF 70-200mm f/2.8L USM lens

[jc8]

I have a canon 70-200 EF 2.8 USM lens, version I with no IS, and I need to get a tripod mount ring for it.  What version of the mount fits that lens?

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
