Saturday morning modding
I think im on the right track. Need some denser foam though. This fits nicely but needs a little bit more rigidity. The prototype gasket was the best I could do at midnight and sacrificing an old gun case.

It is an Airaid Throttle body spacer off a 4.2 envoy/trailblazer. You can barely see it in the picture. It is red. I got it for super cheap off this forum from a member. Idk if it does anything other than make noise though
maybe make a thread on it and some 3800 guys could help you out that have made FWIs before.
