Thanks KJay. I was just a little concerned. I can stick my finger into the housing and feel where the top of the blade is, and it looks like it's just 1/4 inch from where the screw will go in at, but if you've put them in like that and the instructions say that's the way to go, I guess I'll try it. I'll be holding my breath as I screw it in though:) Thanks again, Steve..
