How to get into the trunk of a 65 Barracuda????

Thanks for the ideas. LOL, sorry for being a newbie to Barracuda's. I thought this was a speaker cover. There was nothing behind it. Is this the correct cover? I had removed the body plug under the spare and yep there is a spare in the way. BTW, the car is a Formula S 4 speed that has been stored inside for around 30 years. Last stickered in 85. Any pictures of the latches on the back board?
