To be a friendly member here, I'll input my view on this swap.
It is a very easy and satisfying swap, I was able to do it in under an hour with my little brother there to help me. We're 16 and 15 and did this by ourrselves.
I told Conor this part but I wanted to be fair and let everyone know:
Unless you have sufficient money for this, I do NOT recommend swapping these by shipping, if you can help it. It ran me $400 to do it with materials and everything, boxing them was a *****. The trim panel for the bench, which is a very lightweight but long piece ran me $150 alone.
