Will be there Friday, Sunday, and Monday. Hope to run in to some of you guys. I put Sparky spark attestors on my oval powercore 2's, and I had to file down the the rib that runs down the top side of the silencer. But I got em on. I have seen dunlands(or DAR) run out of them on holidays, so if there is another place you can get them before hand, it might be a good idea.
