If you have the drum front and rear, as I remember all the spokes are the same except there are inside spokes and outside spokes, the bent ends are different lengths. At the time I got the single gauge spokes for $75 a set, the double gauge spokes (like the originals) were $150. I got the single being cheap. If you want just call or email Mike and he will set you up with what you want instead of guessing on the part numbers. The SS spokes come with SS nipples, just use a lot of nickel anti-seize. Once you do one, it doesn't take long, what takes the time is getting it centered on the spindle on the bike. I was pretty anal about it and it didn't take long. I got the run-out and wobble under 1/2mm and the rim centered on the spine within 1mm, you have to do that on the bike.
If your hubs are dusty and dirty, clean them up with one of those big metal brushes. You can polish the edges if you like.
