About half way through production in 36 chevy they switched the doors to all steel and cut out a few other pieces of wood in both standard & master models.
They did in the Standard but not the master...
I have had a 36 master chevy for 30 years..actually more than one and I have searched the world and never heard of or seen a 36 master
at least in the 2dr c-dan that had a steel door
I have a factory parts body and parts manual and there is no steel dr for the 36 master listed in the manual nor in all the years I have looked or wished I could never find one or heard of any...I have heard the rumor and some guys thought they heard that but if they did I know about a hundred other guys with 36 masters that would like to see one ..I know lots of guys have done the conversion to steel tubing including me but it is a lot of work and time ..If your doing a rod I would do it to..I have known several guys who just did the doors and the pillars as the stuff around the windows is not usually rotted to bad..I have also made patterns of the old wood and made new wood to install into them as well
