weiand upper pulley jegs

Never mind, after a 35 min wait the guy from weiand said the pulleys they sell work for what ever size 144 142 supercharger u have. I said that's what I need to know then. He asked the center to center front to back on the 4 bolts that hold down the supercharger, I gave him my measurements and he said he doesn't have anything in his books for that measurement. Claimed to not know anything about my little b&m. He said they wouldn't have any pulleys that would fit it an I would probably have to have one made. He didn't even give me the measurements for the pulleys they sell in the size I was looking at. I was thinking I could have had it turned or something to make it fit but I guess not. Anyway hope this saves someone else the time of being on hold. I thought they may have been a little more helpful but I guess when your that busy there's a lot more customers u can put on hold. The search continues.
