I contacted them via email and they got back to me in less than 24hrs apparently they have gotten a lot of questions about a 40 option. They said that they will hope to have something for us by spring 2009Thank Johnny C! I've actually got an Eshan top coming this week but these Can-Back tops looks really nice and know a ton of people are looking for something similar. I think the ability to attach a rack to the soft top bows is a great feature. I was considering building a bumper/windshield mounted rack system for my truck but that combined with my Eshan bows and my full cage my rig would look like a spider web when the top was off. Just thought some of the people that were still looking for tops might be interested in contacting the Can-Back guys to let them know of the major interest out there for a 40 top.
