Rare Spares are the only local company that supply 240Z floors, 2 seater rear slam panel, lower front guard patches and sills.
The rest are either supplied by Z Store/MSA or TABCO.
You won't find Sill pressings for your 2+2 - you will have to buy 3 standard length one's & extend them to suit.
I can build panels as necessary, but I'd want the Zed in front of me to measure off. It's also more costly this way...
