I wouldnt have thought that it was worth copying at that price. thanks for the info, when I do mine ,i will order a set from you
 
The replacement O'ring kits available sometimes have red O'rings. OK everywhere else but NOT on NRVs. Specially if the location cone is worn. To soft.
Wammers what size are the o-rings for NRV please - about to refurb my block

Don't have a clue. Get an O'ring kit off eBay, but look around some of them are ridiculous money. Cheapest one i used to use listed in my EAS "How to" not available at the moment unfortunately.
