I am new to this forum and was just looking for some general information on some rust repair I will be doing soon. My z has some rust on the hatch sill plate and I bought a new panel that was cut out from a parts car. The piece I bought is the sill and the latch mechanism. The piece has the about 6 inches of the tail light panel attached underneath it also. I have also attached a picture of the piece I bought for reference. I was just looking for any advice on replacing this part. I was planning on just cutting out the part on my car and welding in the new one but I have never done this before so I'm just looking for anyone who has done something like this.
Thanks in advance!
