The jets look like the ones you posted. Are all jets that look like that the same external size and taper?
the taper should all be the same (due to them all using the same type of AN hose/fitting being the sealing point), however, the base of the jet (where it slides into the jet holder) i have seen in different diameters, this is where the calipers i mentioned may come in handy to ensure your getting the proper size. IIRC the ones i linked on ebay SHOULD be the correct diameter, since their listing mentions specific makes of kits... Nitrous Works being one of the ones listed. also, if you didnt want to buy that many jets, i believe there are guys with ebay auctions for fewer jets, but you can still pick from an assortment.
