I would suggest calling the shop at 1-888-654-4450 press 2 and then the # key. Explain what you want to do and ask how much it will cost. As for a return for something theat is to heavy or won't fit in an application, we will do our best to help out as much as we can. We do list all the pack weights and dimensions for each pack on the website to help you in your decision making. We cannot however take packs back in all cases. We make the packs as you order them. So we can't take a pack back and then try to sell it to someone else that is expecting a new fresh pack. it wouldn't be right. You need to be very carefull when selecting what you need and if your not sure ask us first. Chances are we have run into the situation already and can tell you wether it will work or not.

Thanks,

Jason
