I have a Fiberglass bonnet and need to put a scope in so that the carbs don't hit the bonnet, Any suggestions how I start this?

trace round the scoop and cut it out in paper, place on the bonnet and see whare you want it, re cut the paper template 10mm smaller and cut a whole in the bonnet

how to affix it to the bonnet depends n the mating surface angles really.

...exchange for a power bulged bonnet...

Dare I ask what a power buldge bonnet is?

One of their bonnets with one of their power bulges already built into it!

P.S. Scoop aka power bulge!
