Joe,
There were four types of "coupes" for 28-29...Standard Coupe, Special Coupe, Business Coupe and Sport Coupe...for which type of "coupe" are you reffering to?

Joetx.. If you use the "search" tab at the heading on the forum page, type the body style you want to look at (eg. Special, Sport, etc.) and tons of information will be available to shift through. I think you're asking the question about the "belt-rail" section, and how the top is formed to the body panels. My avatar shows a '29 Special Coupe.. kb
Yes, the upper quarters and lower quarters as well as the center panel all unbolt on the 1928-1929 coupes. On 1930-31 coupe, only the cente panel unbolt- the quarters are each all one piece
