Good looking project, someone would be glad to have it. A good place to check out would be the WOKR (Willys Overland Knight Registry) web site and forum, just do a web search. Post there, you may get some interest. Looking at your car, it’s a 28, the 1928 model year serial #s ran 110345-316405. There should be a serial # on the back end of the frame just above the spring shackle on the right hand side, the # should be pretty close to the engine #. Another thing to look at, there is an assembly date stamped into the engine block on the left hand side, circled in red. Good Luck.
