I don't know about LCF "floor support" but just try to wind it out...tilt and up and tilt and up and forward and tilt and up and..... If it won't go, let her back down. Tranny is four bolts and 130 lbs. Make sure clutch fork is all loose. Better with all front parts off, radiator, support and whatever an LCF has. Don't want to try and hop over tall stuff. If you are doing some kind of major swap, you would want the front clip off anyway to fab and mock up.
