I dont know the ebay spacers your referring to but do they have studs pressed in to them like the H&R's so you dont have to replace the ones in your hub with new extra long ones, or are they just a spacer and nothing else? I wouldnt want to buy spacers that have studs pressed in them that are of a unknown origin/quality/country. Here is what all comes in the H&R I linked to. Yes, you can also find these cheaper but I figured I'd give Pelican a plug first.
