confirming coronet model

does someone have the book where you can find where & when your car was made? when I purchased my car first thing I did was change trunk lock.was a "late dodge" lock ,so here im thinking I have a "later made" 50 model,then I bought a antenna to fill hole on "passenger" side fender,when I noticed all other 50 model are on drivers side,but noticed the meadowbrooks have on right side.now im trying to find replacement hinges for hood,after hitting wall after sending pictures out,i discovered by viewing plenty of youtube shots of engine bays ,that my 1950 coronet,actually has the bracket set up for a 1949.so is it mixed breed or what? so hoping look up may help for ordering parts. does anyone have same situation?{ yes title says 1950 coronet also grille,interior.etc states its a coronet}

 

Early Mopars are like that you probably have an early 50 car, the same issue arises with the 47/48 4dr sedans with the door configuration.

 

If there was parts from the inventor of the previous year they were used when ever the could,,as with most makes you have early and late production.

You should be able to find information that helps establish production dates on the internet,,possible someone here may already researched that information and can be of assistance.HRP
