mtntrk: I concur w Dennis about putting something on top of the bolt to hold it down from the top, but you're right about putting those fasteners on from the bottom. I did the bed on my 48 a few years ago and was also frustrated until I had a lightbulb moment: drop the nut into your socket and then position your lock washer and flat washer on the edge of the socket; then use masking tape wrapped simultaneously onto the outer diameter of the flat washer and the socket to hold it all together while you get the nut started onto the carriage bolt. Worked like a charm. Good luck....Dave
