I built a drive in push out front wheel clamp when I did my rear main seal. If you have a welder they can be built or they have been made out of wood. Virtually what you are aiming at is two braced vertical supports wide enough to allow your wheel in, additional tie down straps can be added. Mine resides in the back shed and is a pain to extract but if needed pictures can be taken and posted. it is no work of art and was thrown together out of what I had at the time in a very short time. They can be bought new on line however they have a pivoting action that could make the bike just as hard to extract.
