Replacement relay for SX-1050

I'm restoring a SX-1050 for a friend of mine, and I was wondering what I should replace the relay with. Somebody was messing with it before I was and damaged one of the contacts, so it needs replaced. Relay is a MS4U 48VDC, part number is ASR-020. Can anybody help with this?

Edit: will this work? MY4-02-DC48

That's the one...
 
Quick question, does this need the flyback diode and where is it put? I did a search and couldn't find anything definite.
 
Now that I study the schematic, I see it now. Thanks Overload! This is my first time restoring a SX-1050, so I'm not too familiar with it, and I know that the SX-950 needed the diode added, which is why I was asking on this one (though I should have studied the schematic.)

Hi, I'm replacing the same relay, did you have to replace D9, if so do you have a mouser part #? or where you wondering if you had to add one? I'm new to this so I just want make sure I'm replacing everything I need to, thanks.

No, replacing that diode is not necessary.
