And then there were two:
This morning the second side skirt arrived. Next these need to be installed for a test fit before paint. Once they're in colour then I'll need to let them cure for a while before wrapping them in 3M.
Along with the skirt came a small pack of clips, I'll check to see if any need to be swapped out in order to install the ST pieces; I also have to order new front mud flaps to fit them.
Also waiting to be installed now is a replacement MAF sensor housing. Thanks to Mason for that!
