New Heritage rear panel arrived. Had to order this from UK, as I couldn't find it in the US. Mossmotors US tried to convince me that the GT uses the same part as the roadster, as they don't even list the part for the GT. Fellow on the phone wanted to argue with me about it, despite showing him the different part numbers at BMH. Moss UK had the correct part, and cost including shipping from UK was about $160 less than buying the incorrect roadster version from Moss US.
Found a good used tailgate. It even appears to be the same year or close, based on the emblem holes location. This one should only require normal paint prep.
Moving around to the back, after a closer inspection, I found the whole rear of the car has had body "repairs". I stripped off some of the loose paint and bondo to get a better idea of what I'm dealing with. Basically, the entire rear panel is sculpted out of bondo up to 1/4" thick or more. The car was bumped in the rear at some point. There's no point trying to strip this any further. The whole lot will need cutting out and replaced. The hatch will need to be replaced as well.
