With the cost of fuses today I would replace that fuse box with a breaker box. Probably find something used on craigs list. It should cost less then the price of two boxes of fuses.

You can buy a new panel for $15 from Hoe Depot. Double that for two breakers. or get a used panel with breakers on ebay. Probably pay more for shipping then a new panel and breakers would cost.
