THe .04 could be replaced by .047 or even a .05. The black stripe on the old wax cap indicates the outside foil, and is of no particular importance 99.9% of the time. You can always reverse the leads if it becomes critical. The outside foil was typically tied to the ground or B- in the original manufacture of bypass circuits, and remained irrelevant in other applications. Modern equivalents are much smaller, and therefore have much less tendency to radiate or absorb any external signal. Someone once commented that the left side of the capacitor, when you read the value, is the outside foil, but I can't say that is true. Someone out there might know.

Just follow the original lead dress, insulate the leads with shrink wrap, and do one at a time and you'll be fine. If you need to extend the leads, do so before slipping on the heat shrink, and place the new cap where the old one was.

Take a few pictures first, so you will know where to put everything.
