This was a perfect replacement for my 2003 Ford F-150 Snugtop Camper Shell. I could not find the original Suspa C16-16805 stand. Suspa C16-20651 has the same characteristics. Sizes are the same when compressed and expanded fits a 10mm bullet, just like my original. The only difference I noticed is that this rack is rated at 39lbs versus my original 40lbs. Don't think 1 pound makes a difference, it works great and is very easy to install.
