As promised that sketch and a descript:
Having a small garage (13' x 28' x 9') one quickly becomes space conscientious and I kept thinking if that roll back door wasn't there, I could put in a car lift.

Not to make a first post a bit know it all, but take a 0.375" water pipe 10"-14" long and cut some teeth on the end, chuck it up in your drill and auger your way though. The stuck bit will be you guide on the inside of the handle bar.
