Any one know where else I can find a heater plenum other than the ones in CBS or europa spares? I need a 44 mm inlet and a duct that is 250mm long approx.

thanks

I'd be interested too- the aforementioned ones seem to be made from a pretty rare form of unobtainium considering that most people would just vac-form them out of plastic....

I've seen people use vacuum attachments for plenums. Might find one the size you need. Other thing to do is just go oversize and seal it to the bottom of the dash. Then cut whatever size/shape hole you want.
