Ah, OK! Well I’m not sure how bad the fight was, but it’s usually recommended to take a 2-3 month break when a fight occurs that is bad enough to break skin or injures a rabbit.
So, if they were scuffling a little and you stopped it before it got too bad (maybe just some fur pulled?), I would just keep them separate for 6 weeks more until they settle after their neuter, then follow the pre-bonding steps I mentioned already. But, IF one of them was hurt in the fight (even just broken skin that scabbed from a bite), then I would give it another 8-12 weeks before starting pre-bonding.
As hard as it can be to be patient, these early steps can be really important for success later.
It sounds like you are doing the best you can in the situation you have!
