Did you buy the universal one or the supra spec one?
I bought once 2 of them the universal one did not come with the bolt and the one for the supra did.
Still I don't known but if they removed it, must have been for a good reason, as I didn't see any price change.
I've boughten both ss bov's in universal style. But the first one I bout was a year and half ago. When the new one came in, I knew something was different but couldn't figure out what it was. Then I realized it didn't have the valve adjustment in the back anymore. Also It seemed like the new bov seemed like it was made thinner(where it goes into the flange) cause I could spin the new bov so easily, where as the other one I could only move it unless gave it some pressure. Have any of you guys recently purchased a new ss bov lately?
