I have just finished a 20 year restoration of a Windsor Ontario built Model 72 coupe R/S. It is a close to original as I can possibly get it. I can not find an oilfilter. Many pieces had to be manufactured (i.e bolts, steering wheel light and gas control levers. The wood frame was in excellent shape but I did obtain a Fisher Body Service Manual. It is interesting that the manual for Chevolet bodies and Chrysler bodies appear to have been basically identical. I wish you every success with your project.
