The two metal pieces CB Performance has, and they come with the rubber
seals. I would bet they have the rubber pieces available seperatly too.
http://www.cbperformance.com/catalog.asp?ProductID=274
The soft seals are nothing more than foam weather stripping availble at
you local hardware store, home depot, etc... |

Wich is better the late or early FI shroud?
The early shroud looks to be better due to the large slot,
But there must be a reason why they changed right?
I have got two late FI shrouds and one normal doghouse shroud with large negative slot, can i remove the venturi and weld it too the normal shroud as too have better cooling? |
