barracuda fastback carpet

First I would like to thank all the helpful people who have made my project easier by sharing their knowledge, so onto my next problem. I ordered a 68 fastback carpet set from legendary and it was drop shipped from alltrim. The back seat carpet, although marked fastback does not extend back to cover the gap between the rear seat and the quarter panel. I called alltrim and they said they only make one style [if this is correct why is it tagged fastback?] Do I have the wrong vendor? I hate to wait another couple weeks to get this resolved, if all the carpet sets are like this maybe I will just go ahead and install it...
