I have a set of triple webers with a Cannon 1 pc intake that someone wants to buy from me, but he has a `73 240z. Will they fit? They came off an `83 280zx. Seems like the intake has 2 different bolt patterns. One where the bolts go through the manifold, and the ones that were actually being used where a bolt with a large washer clamps over the manifold ears. I linked to a pic of them if it helps. If anyone can help, it would be appreciated. Thanks.
