Good Replacement for MEPCO's Electrolytic Caps 1000uF/300V, (35mm Ø), used in VTL Amps e. g. Compact 100 and Stereo 50)

For replacement of this aged caps most important is to know, which good available brand and model has the lowest value for ESR with a diameter
of 35-36 mm and in a range of 470-2200uF/300-450VDC

The original length on VTL's Compact 100 is 150mm, but this value isn't critical in order the available space.
The exact type naming from MEPCO is follow: "3186BH102T300BRA2" - go to first attachment.
Due to the small diameter and screw terminals at the same time (sometimes without extra PCB as to see on the fourth image, sometimes with extra PCB as to see on last image), the number of available low ESR series is unfortunately limited.
Maybe one of the member knows a perfect suitable version as a replacement.

Thank you very much for an advice

P.S.: On the web I have found this 35/36mm Ø versions:
PEH200XD3470MU2 (RIFA)
ALS70A112DE350 (KEMET formerly BHC/Aerovox)
MAL210216471E3 (Vishay, formerly BC/Philips Components)
LQR2G681MSEC (Nichicon)
ALS30A471DE400 (KEMET formerly BHC/Aerovox)
