What are your plans for the area? Are you going to be just using it to rebuild this truck or are we looking long term? You might talk your way into a re-builders shop to have a look. If you need to plumb an air compressor TPTools has a nice diagram online. Sounds like a nice size shop. I have to roll my truck to one side to blow my nose. Fortunately I picked up some Harbor Freight wheel jacks for 90% off. I am not sure I would have paid the $100 but ten bucks was to good to pass up.
