I fitted the Librands manifold to my 1800 Zetec a few years ago. Fitting was quite straightforward, but be aware you will need a deep socket to fit the nuts, as the studs protruding from the head are quite long. Also, I found I needed to wedge the pipe, where it passes through the chassis,to stop it contacting, before fully tightening everything. I guess you could use the old manifold gasket, as it's steel, but that's rather like the 'ha'porth of tar'. Gerry.
