Replacement capacitors for M-508

I have a vintage Integra M-508 2 channel amp whose 8 big electrolytic capacitors have started leaking and need replacement. The original part was 3504197 (or 35D4197, I can't read the old service manual very well) and are Nichicon 10000uF 90V capacitors. I called Onkyo Service Parts and the representative told me they are obsolete and therefore no longer available. On the Nichicon website I did not see anything similar.
Does anyone have an idea about other parts that I could use to replace them?
