Need a new carb flange/holder part. Does anyone know if there are any options for the savage which are better than stock? Need something really solid with a strong seal to hold boost.

I've destroyed two of them so far. However, it's more of a tuning matter rather than a boost factor. I just wanted to see if there were any other options before I find a replacement (not sure even the best place to get em?) I like the o-ring seal type the best.

pretty sure yeah, even if it was.. I still need a new one. What are the best ones available?
