After a Pipercross base plate. Any old condition ~ only to be used as a template for a composite part.

I cut my own plate using the new filter as a dimensional template, here's a link to some dxf & pdf drawings if you don't have a filter to hand, you can modify to suit your throttle bodies/carbs.
If you're using it to make a mould, you can use something nice and easy to cut & shape.

Thanks Dave. That will save me a few quid. Much appreciated.
