Thanks guys, I know all about the flap grinding discs, have several on hand for mods. but don't have access to a mig - yet!!!.

I suspect I could hire one but on the timeframe I would like to work to, ie no rush, this would work out as extremely expensive, assuming they can be hired.

So if I am going to chop into a made product, am I better to use the free option that will need far more work to make it fit, or an item I will have to pay for but that is far closer to the fitting mark?

The second option is the RMC extractors and these are a marginally larger tube diameter than the standard extractors. How does the larger size affect engine performance/operation?

Cheers

Steve
