Are you sure you have 4 different copies? You may have different versions out there but there should only be 1 on file. You can find the right version at the county courthouse records office. Get that copy and then work from there.
There are other posts on here about this very subject. My experience it took me about 2 years to change/update our CC&R's and By-laws. It was a required 90% for the CC&R's and a 75% for By-laws. Both don't have to be changed at the same time but it's not a good idea NOT to do it. CC&R's override any descrepencies between the CC&R's and by-laws.
Expect to have court filing costs and copy fees. It cost us about $700 in court filing fees. We got a board member with copier access to make copies. You can also make electronic versions. (PDF file for NO modification ability). Make sure the signatures are NOT renter's. Only the homeowner can sign the paperwork.
A good hint is that if you can't have a special meeting to change the rules (as required in some CC&R's to change) you can have another petition signed giving up the right to one. Essentially, this allows you to go door to door to get your votes. One petition will be for agreeing NOT to meet in a special meeting and the other petition is for the actual change. Ask your lawyer about this. It may help.
Review a few other posts on here and you will find additonal help. Good luck! It was one of the worst things I ever had to do besides remove dog doo-doo from the swimming pool as president!
