Mc2300 Mc2205 Power supply caps

Hello, I'm going to change the supply caps on my MC2205 and MC2300.
The right dimension is 73mm*105mm.
Specs: 39000uF, 40VDC, t85°C.

On Mouser I'Ve found two types of capacitor:

1) https://www.mouser.it/ProductDetail/661-36DY393F075DL2B
39000 uF, 75 VDC, Torlerance: - 10 %, + 50 %, dimensions 76 mm (3 in)*93 mm (3.625 in)

2) https://www.mouser.it/ProductDetail/598-DCM413U050DC2B
41000 uF, 50 VDC, Tolerance - 10 %, + 75 %, dimensions: 76 mm (3 in) *105 mm (4.125 in)

So, the first one has the same capacitance as the original one but it reaches 75VDC and it is shorther.
The second one has the same dimensions, but bigger capacitacne and reaches 50VDC.

Be in mind the connectors mus be insulted like this:

Which one would you suggest? Thanks in advance
 
Honestly both would work fine. I don't think there is much if any impact to the unit aside from improved tolerances. I've done many power cap swaps and never noted a diff in performance (unless the old cap was defective in the first place which was only the case once). I'm personally at the point now where I would only mess with them if I ruled out everything else.
 
I used the Nippon-Chemicon in my 2205. Works fine. The CDE one is twice the price and it's not in stock anyway.
 
I planned to restuff the existing multi-cap with pencil caps but could not even get it removed. Tried a drill and dremel and neither could grip the rivets. Also too much movement of the frame where the PS caps are mounted led to a broken wire from the stereo/mono switch. Any tricks besides just mounting the caps under the chassis?
