hello,

I am wondering what is the best tool to be used for those nuts, the ones with the ridges on them. Especially that they are in a very tight space.

Thank you,

Just for anyone else that runs into a similar problem, after some.more research, I ended up usimg a split rin wrench, wasn't super easy, but with lots of small twists, I managed to get the nuts out then back in!
