Garage Door Installer Needed

[Sigfan220]

I have a new garage door but my garage does not have enough clear height to install per the instructions. I played with it for a while but can't figure out what needs to be done to get it to work. The old door worked fine before it rotted apart so there must be some way. I just don't care to monkey with it anymore. PM me if you are interested. I am in Crystal MN. It's a small door, 8'x7' with very little clear height.
