Not sure about the standard manifold on your car Mike, and the difference between that and the standard one I have...I do know that the aftermarket one which I am selling is a definite upgrade over the standard one though. its only 1000ks old and has no cracks.
Sorry I haven't contacted you in a while. Still interested in the sump. I'm going to Melbourne tomorrow but I will contact you next Wednesday/Thursday about it if that's alright?
