Yeah they are, i found a set of freshly built N1's that were selling cheaper than what it would cost me just to replace the seals so i bought them.. i got them delivered to my work today and i must say who ever rebuilt them did a great job, everything is top notch. They look brand spanking new. So next wednesday the old N1's come out and these ones go back in, and hopefully i can take her out friday nyte and meet some of you guys at the usual meet if you's still hang out there.
