That is what I was worried about with the "generic" kind. If I went with the "lollipop" style, I would make sure that they have the part that slides into the track end. I just feel more comfortable going with the other style similar to the Tuggnut. Thank you for your input!

edit: Good advise on the wingnut mod! I couldn't seem to find anything like that besides the tuggnut but I will definitely look for some wingnut bolts at the store when I buy some tugs.
