And while you have the tape measure out, measure the height of YOUR door. It depends on how far up the door goes-some do not completely clear the door frame.[/QUOTE
I had this same issue. My cruiser is SUA on 35's and a little over 7 feet tall with the soft top on. My old 1960's tilt up style garage door only gave me about 6 foot 10 inches of clearance and sat below the header when open. Had to remove the top, air down the tires and push the door up over the roll bar while backing in just to fit it in there, then had to air up and install a top every time I wanted to drive it; what a pain in the butt!

This Summer I removed the old door, installed the soft top and aired up in the garage so the cruiser was a it's normal height. Then I used a laser level on the highest point of the top to ensure I cut enough header out for clearance which ended up being about 4 inches. Went crazy with a sawzall and belt sander for a couple of hours until I could get the cruiser in and out without any issues. Reinforced the header then replaced the garage door with a 8 foot tall, roll up storage unit style door that locks from the inside and rolls up well past the header. After a little creative trim work and paint, the door looks great.
Very happy with the results, only draw back is I do not have the ability to remote open the door anymore. Hope you don't have to go as extreme as I did to get your cruiser to fit. I would have much rather spent the few hundred $ I paid for the door on cruiser modifications but I feel the time I save not having to air up and install a top every time I drive is worth it. Good luck!
