Those 6287-F and similar 0.3 uF blocks actually contain two 0.15 uF caps wired in partial parallel (one end common and wired together internally, the other two ends wired together at the terminals). A new 0.33 uF film cap probably won't fit in the block, but two new 0.15 uF film caps will (barely) fit inside...which is probably why Philco did it that way to begin with.
