Hi Jeff, I found this on the Boss 302 site. I think this is what mine came with. Do you?
Going to make me do some more digging
According to what I see in examples that interior (as we see it) does not match what yours would have. Appears to be code EA which decodes as a black Delux interior installed/available for 70 Boss 302 and 70 convertibles not sportroofs and coupes. This is one reason its been more of a challenge to find pictures of the TA interior
If we look at at some of the published descriptions of your interior they show "Deluxe " or "Decor" Interior and notes that these came with standard door panels as shown in the pictures I posted. If we expand outside of your specific interior codes and look at other color combinations under the same Deluxe/or Decor interiors we can find some other examples that can hopefully supply some details to help you.
Unfortunately the VIN tags made of vinyl attached to the doors often are difficult to make out after all these years so will also look for other confirmations of interior types this time through. Also sorry for some of the pictures. I'm often focused on other areas and details during the limited time I got with some of these cars.
So now focusing more on the seat coverings
70 listed as being ordered with Delux Interior from one of the nicest unrestored Boss 429's in the country
Another very nice unrestored Boss 429 with a TW (White Delux) interior. Same option/family just different color
