Hey guys! Happy to be part of the Acura club. I got a great price on a 2005 TSX.. however, it has some drawbacks. It was hit in the back a while ago which caused some damage to trunk lid and bumper cover. The trunk works fine, but the cosmetic issues are a bit of a bummer. I'd like to change out these parts - but I just wanna make sure it's the actual parts causing the issues.
Today, I changed out the L rear tail light because it had a crack in it and took off the entire rear bumper to get it out/in. What I saw was - the black metal beam behind the bumper cover was slightly bent, also, the silver part of the body (shown in pics) was bent as well. The trunk and bumper do not line up well with the body.

Would getting a new bumper and trunk lid help these cosmetic issues? Please see pictures. What's a good website to buy these parts at? I bought my tail light at a junk yard, but bumpers and lids seem harder to come by.
I appreciate all help!
