It's not every day that you get a chance to work on a steam powered vehicle. This is a '37 Packard that was converted to steam in 1940. The guy who built this used early 20's Stanley Steamer parts...actually, he used the entire drive train and then some from the Stanley. It's a bit of impressive engineering.
The owner did get it running using compressed air...here's a video.
There were some issues that needed attention on the rear axle so it was dropped off at the shop for a rebuild.
