Hi all, I recently puchased a manifold and plenum spacer from Mace and went to install it today. The instructions are clear (even if i only have them printed in blue. Stupid printer ). Anyway. I put the spacer up against the old gasket to check it out and there is a bit missing. I check the manifold and the underside of the plenum and lo-n-behold it appears i have a different design to what was shown in the instructions. Im just going to put the engine back together sans manifold spacer atm till i get some clarification. Posted below are pics of the spacer aligned with the gasket. As you can see there is a channel that runs from the top (in the pics) to the bottom. The spacer is missing this and if i put it on would leave this bottom part exposed. Any suggestions/help?
