I have a Superior Airflow (aka. Extreme Velocity) Composite carb bonnet that I used for my blowthru build and now selling to order an aluminum one due to running high boost. It is a two piece bonnet as you can see by the 4 bolts. It has been put together with a bead of gasket sealant as recommended, but can still be taken back apart. Could be used an a N/A carb build to make a nice cold air intake system or used on a low boost build. Asking $55 shipped.
Pics available if interested.
