PO muck jobs on our cars are a blessing in disguise when it comes to learning how to work on these cars correctly, truly
every old classic is a particular case. a study in itself. like anything professional, you need to study the subject closely first (best done at disassembly for resto). then you plan how to proceed further with the job. never start a resto without starting on the sketch board first (and no i dont mean a literal sketch board, rather a mental version)
a sketch board is where you completely go through what needs to be done and how it needs to be done, and how to go about it, so that it will be both, cost effective and correct. for instance its on the sketch board that you note what body/mechanical jobs need to be done in pairs and what special tools/treatment would be required to do those particular jobs 'correctly'.
for instance, while disassembly, with these old cars its a norm that you break a rusted screw in a screw hole while trying to remove it. for such times, i carry a permanent bold marker and when a screw breaks, i circle it with the marker. then at the stage of media blasting/cleaning with a wire brush, i keep an undersized drill bit/drill, tap set close by to first drill through the broken screw then clean the threads by chasing the threads with correct sized tap. once done, i blast/clean the panel and then there remains no job/mark that was put there reminding me of which screw holes need cleaning up. this way, its both time saving as well as cost effective, not to mention correct - without forgetting a single broken screw hole unaddressed
we'll follow through this sometime in future again as i dont want to get it all boring for the readers
