I need a 4 bolt style- it'll be around 50mm. Doesn't matter what brand it is. I don't even mind it being an Ebay Special but I do need to know what PSI the spring is for. Hit me up with your offers. Blowoff is the same deal- I'm not being picky, I can make whatever you have work as long as the internal seals are good.
Thanks,
Kevin
