Ok so I bought a used blaster rear shock with rezzie on eBay for 40 bucks, just got it today and superficially it looks pretty decent aside from a slight scrape/gouge on the reservoir, the problem is that I've been looking for a similar shock to compare it to and there are none! Anyone have any insight on this matter? The only numbers/markings I can find on it are A2 1S300 on the arm of the reservoir. I would like to post pics if someone would be so kind as to tell me how lol. Any ideas?
