The sales sheets seem to be a little inaccurate, in that there is no convertible top switch(I believe all were power operated), the rear seat bun seems to be a little long from the inner quarter to the first seam. Convertibles are about 5" inches there, I believe coupes are about 7-8" there. These appear to be coupe rear seats. Also in the same photo the left rear inside seams to curve away from the back, like a coupe would. The convertible seat would meet at 90 degree angles with the inner quarter. Other things of interest in that sales book: the door mirrors are different on the two cars and the one with the sport mirror only to have one mirror. While not that significant, I believe we should not use these pictures to guide our understanding of what Ford offered. I will agree the standard and deluxe doors were available. I believe all convertible seats were knitted vinyl.
All 1971 Mustang convertibles came with a power top. As far as the picture not showing the actual switch, as you had stated, “Not that significant”. Ford like most manufacturers have used and reused photos for a variety of advertisements.
A back seat in a convertible is not the same size as a coupe. Additional clearance is needed for the convertible top linkage mechanism. Although Ford redesigned the 1971 convertible top assembly so that the stack was wider and linkage simplified so that the stack sat back further and lower in the well. This resulted in more shoulder and elbow room over the previous years.
The standard, base model convertible came standard with an all vinyl thin shell construction high back bucket seat. Any convertible could have been ordered with the décor group. This option offered a choice of knitted vinyl or cloth & vinyl. However one exception was when a convertible was ordered with the décor group, knitted vinyl was required. This makes sense when one considers driving with the top down, how quickly dirt could become embedded in a cloth seat. The number of 71-73 Mustangs entered in MCA national shows is small and unfortunately getting smaller. There have been some shows were I have only judged 2 or 3 cars from those years in the concours class. Almost all convertibles entered now are upgraded models. If not purchased that way, the current owner upgrades due to personal preference. One would think that Ford only built convertibles with “hockey stripes”, ram air hoods and magnum 500 wheels. It is unusual to see a plain Jane convertible.
Photos, unfortunately are the only verifiable means we have today to determine what Ford had intended 43 years ago. So fans today consider factory photos from the era “gold” and scrutinize them intently. Most show cars are over restored and do not truly represent what was on the show room floor in 1971.
The 1971 Convertible came with "standard" & "upgraded" interiors, including door panels when the "Decor Group" was purchased for a suggested list price of $92.10 for a convertible.
I has seen and judged 1971 Mustang convertibles at MCA national meets for the past 19 years now.
I've attached a few sheets taken from Ford records from the 1970/71 time frame. Notice the sheet with the header "Mustang Convertible" it clearly shows a base model convertible with standard interior and has a description written up in the "Interior" paragraph. Also included is a sales price sheet showing cost of Decor Group.
Ford is noted for changes, not always documented. The only documented change that I have been able to verify for the 1971 convertible is a late model change where tinted windshields were made standard equipment. Also attached FYI.
Hope this helps.

Thanks Mac for the info... clearly, the brochure shows a standard interior with standard door panels.. but what do you make of my car with Decor Group listed but NO moulded door panels on car or on window sticker? How would this car be judge in an MCA show?
After looking at the photos (very clear I might add) of your vehicle certification label, I can see a build up of red paint around the edges. My guess and it is only a guess is that when your car was repainted, the door panels were changed. Most original molded door trim panels, especially the drivers side would crack where the driver would rest his elbow while driving and are often replaced.
You are correct though in stating that your car came with the decor group option and should have had the molded panels. In a concours class you would loose points, in a daily driven or modified class no, as judges expect that as a car is driven, things wear out and are replaced.
Keep in mind in an MCA show, you can enter your car in a number of classes. Checking my 2014 list of classes, you can enter in:
CTE 1971-73 concours trailered
CDE 1971-73 concours driven
CDT 1964-1/2 - 94 concours driven trailered
URA 1964-1/2 - 73 unrestored
THBA 1964-1/2 - 78 thoroughbred
ODD 1971-73 - occassional driven
DDA 1964-1/2 - 73 daily driven
MA 1964-1/2 - 93 modified
DSP 1964-1/2 to present - display
It is up to you to determine how you would like you car judged. Keep in mind that you are entitled to the actual judging sheet via the mail after the show is over. Most owners use it to help improve their cars. Also the name of judge who judged your car is on the cover. You can contact him for more info if needed. Most judges will help as we want to see the hobby continue.
