I have a pair of 90's and replaced the surrounds with a kit that I got from vintageAR. Larry Lilgace is the owner and an expert on vintage ar speakers. He is good to work with. You can probably find surrounds cheaper but I was assured that by getting the kit I would have the right surrounds and quality surrounds and quality glue. The kit comes with good directions and with shims which you will need. If you get into trouble you can contact Larry and he will help you. If you don't want to tackle the refoaming, you can have them refoamed at considerable more cost--maybe as much as $500. for all six drivers if you can't find someone local and they need to be shipped out. The drivers are very heavy.
You don't want to replace the drivers. OEM drivers are no longer available new. The drivers available are only OEM in the sense that they will fit into the cabinets and will be much lower in quality. They won't be 90's anymore. The only way you can get original drivers is to watch for them on ebay or maybe oaktree. Good luck. They are worth refurbishing.
