Rear site for a Marlin 989 M2 ?

[Dagmaar]

I know they are rarer then hens teeth but , what the hay , I thought I'd ask .
Does anyone know where I might find the rear site for a 989 M2 ?
Just picked up this little beaut at the local gun show today . Nice little gun but just won't look as good scoped as with sights so , if anyone has a lead I'd appreciate it .
Thanks all .

Kind of figured it would be quiet , oh well . Have to hit gun shows and see if on turns up .
I understand tech sites are another option , might have to go that route .
