I am looking for baffle measurements for a 67-68 M20F of DXF or DWG files to run thru a water jet.  I have the equipment just not the measurements without reverse copying my decrepit baffles I own right now.

It appears that the files are in the Coca Cola safe.  That said  I am probably going to reverse engineer them. I am still doing research as to the best material to make them out of being 2024 is what I believe to be original then there is SS with a small weight penalty and then 6061 which is easy to form with hand tools.  If I end up doing this by hand no promises but if I get cad files, spitting out a spare set I will let you know.

Consider 5052 for the baffle material instead!  Easy forming, corrosion resistant, etc.  

I've never seen and drawings like this out in the wild, much less a CAD file.  There is a 3rd party company that sells PMA baffles, and they likely reverse-engineered factory sets and got FAA approvals.  There is nothing wrong with what you're trying to do, but I would prepare to do it the hard way by using your set as a pattern and starting from there.
