Need help with OP 1-2 lvl 61

I’ve tried more times than I care to admit. If someone was willing to run through it with me real quick that would be awesome. I have a lvl 61 zerker if it matters. I want to be able to farm for a legendary gunzerker mod.
I work weekends so I’m around Monday thru Thursday. Thanks in advance!

To get that class mod you need to farm tubbies.

Don’t I need OP lvl 1 for it to drop?

No. You need to be level 62+, and you can’t get OP levels until your hit level 80.
