Installing rocker panels on a 1936 ford coupe is far beyond a normal DIY project. Normally this type operation is done by skilled metal craftsmen that have been doing body work for years. Most average body shop techs wouldn’t even tackle this, it is reserved for the pros at a body shop. It is sort of like jumping in the pilots seat and saying give me a book on how to fly this baby, and we will go for a ride. Well maybe not like that, but you probably get what I am saying. Now if you are real good with metal, and you have welding equipment, it is possible that you can install these but it takes a lot of skill, and there is no instruction manual. My suggestion for guidance is to join classic car clubs on the net that deal with this type vehicle and go to their forums and post asking if any of the members have any photos of rocker installs on their 36 ford coupe. Many times you will be able to find detailed writeups on installs like this, that will never be published. You will need a little luck to get good info, bet seeing there is no manual it is worth a try. Some of these posts on classic car websites are better than any repair manual, because these people are personate about their vehicles, and it shows in the details they go to. Lots of times people don’t replace the whole panel, and many of the replacement panels are not exact copy’s of the original, so that makes for the necessity of custom fitting. It is also common cut off a rocker panel and find there is other supporting metal that needs to be changed too, so it is a pretty dynamic operation. This is why normally only the most experienced body men do these installs. If you have any more questions I am here to help.
