Whats up, long time no see! hope all is well! Ive used the panasonic FC series caps for inputs, 16v 8200uf @ 105c, Look for the brand 'Epcos' caps for the rails as the panasonic TSHA snap-ins are now obsolete..

Just to add:
Digikey has 16V / 8200uF United Chemicons rated 105C/10,000hrs that stand 32mm installed vs. the Panasonics which are close to or about 35mm and (may) contact the bottom plate.
I know the Panasonics were contacting the bottom plate on a MS250 I have during a test fit. The Panasonics aren't rated 10,000 hrs either, not that anybody would actually require a 10,000hr capacitor in practice, but why not if they are available.
Digikey also has 35V / 12,000uF Nichicon rail caps rated 105C/5,000 hours that are 35w x 32mm and will fit perfectly within the printed circles on the PCB of the MS250 and MS275 (not sure about others) and be the same exact height as the input caps. Again, not that 12,000uF is necessary or even recommended, but is an option.
It's a shame Panasonic is getting out of the larger capacitor business as they had some of the best out there in recent times.
I chose Nichicon rails over the Epcos mainly due to familiarity with the brand. Epcos may offer a comparable or even superior product. IDK.
