I need new slow and pilot jets as mine are pretty tore up, I found a NOS keyster kit on eBay, but I want to make sure the part number is correct since in the picture (Part # 7300-317), it looks like the ones in the picture are threaded, and the ones I've pulled out of my carbs (one is a 3d and one is a 722a) are not threaded. Link below to the listing if it helps.
