Unless you absolutely have to have the original capacitor, when it comes to electrolytics, it is not wise to look in the obsolete market---simply because of the shelf life.
Due to advances in manufacturing, most of the odd nomenclature values are either discontinued or have special orders with high minimums.
ie; the same 100mf capacitor of few years ago is available in much smaller package.
You have better luck to go with the next common higher value (100mf) with the same voltage rating which will be perfectly suitable.
As an example, capacitor part number MAL202136101E3 (6x10mm) would be a much better replacement in your application.
