STPR15 rectifier substitute

I know these rarely fail, but I need to replace 2 physically missing in a Rockford Fosgate 800.2.

Mouser has the following:

Vishay VS-MUR1520-M3 200V 15A 22ns recovery $0.98
ON MUR1510G 100V 15A 35ns recovery $1.22
ON MUR1515G 150V 15A 35ns recovery $1.35

Are all of these acceptable substitutes, or is one better than another? Should I change all 4 or just replace the missing 2? Anything else I need to change when substituting these parts? Thank you!
 
The mur1520 seems to be the best choice.

If both of the missing rectifiers are for the same rail, you can probably get by with replacing only the missing rectifiers.

I don't know precisely which board this is and which regulator resistors they're using but I'd think that the 1510s wouldn't withstand the voltage.
 
Hi Perry, it's board PC-3083-D, Punch 800.2. The entire right channel mehsa is missing with all its components, source resistors, and a few other components. Left channel output section is also blown. I'm looking at replacing:

All power supply 5N05HD on both sides with IRF3205 & 47ohm gate resistors.
At minimum the missing right side rectifiers & missing LM337.
All IRF640 & all IRF9640 (right side completely missing, left side blown).
All output source resistors.
All other missing & blown output driver components.
 
This is what I'm dealing with
