And he may even have a preowned gasket that you could have for free
However there is much more to the plenum spacer kit than just a piece of 5/16" ally.
This has been talked about many times by the forum's budding entrepreneurs
My advice would be if you want to see this through then go buy a proper MotorDyne kit and use as a prototype.
Alex you have PM
Hi Martin,
I received your pm on Wednesday but I am still waiting on your preferred shipping address matey.
Royal Mail will not get it to you for the weekend now, so why not just do what has been previously suggested and just pull your top plenum and use your own gasket as a prototype, it only takes 5 minutes to remove it.
Alex.
