Here's how I'm addressing it. If you notice in the pic, the wear strip fits exactly as Southerntruck describes. I decided to use the wear strip as the standard and used it to mark the length of each piece of bed wood. I cut each piece to the new length. I test fit each piece and all of them simply dropped into place. There wasn't a lot of space for lengthwise expansion, but the fit wasn't tight either. They dropped in and fit loosely. I'm hopeful they will be fine. If not, I'll do it again. It only costs me time. Currently, all of the freshly trimmed boards have a new coat of stain/poly and are drying. They'll get a second coat of clear poly tomorrow. I tried to post a pic, but am having website issues. I'll try to add one later. The pic shows what I cut off of each board. Including the blade kerf, it totals about 1/4" of board removed.
