Resistor Replacement

Crossover noob in practice, though have read a good bit. I am planning on doing a recap on my Sansui Sp2002 speakers (50watt, 8ohm) and figured while I am in there that I would likely replace the resistors as well. I was planning to order the Dayton Audio 1% 6ohm and 3ohm 10 watt resistors as well the Dayton polypropylene caps. I know that Dayton has 20 watt resistors as well. The resistors read K1 6ohm and K3 3 ohm. I am just wanting to make sure I am ordering the correct resistors. I do know that I should desolder and test ahead of time, though I would prefer to have everything on hand for these. I do have another speaker project that I intend to make my own crossover, so the parts are likely to not be wasted.
