I assume at 50-63V. You won't get 105C/10K hours in those values unless you build it from a bunch of smaller ones. You may find one, but very expensive. There are 8,000 hours at 105C and that is likely close enough. Nichicon, UCC (United Chemicon), Kemet, TDK, Cornell all have stuff up in that size area and all reputable. The high temp, long life are typically high ripple/low ESR as well. Most caps in audio I have found are 85C/2000 hours. Keep in mind even though they are 105C/10K hours, pretty much all bets are off once you get to about 15-20 years.
I would even trust many of the Asian brands if I knew I was getting the real thing, but unless you are buying from an authorized distributor (Arrow, Mouser, Digikey, Future, Avnet, Mouser ... etc.) you are taking your chances.
