Brake pipe replacement

[stevorally]

Hi everyone

I have a Nova rally car, i am changing the brakepipes from the original copper ones to goodridge braided versions. I have a number of questions.

1. At the master cylinder what are the two different thread sizes for the brake pipe fittings? i think one would be M10x1 but what is the other one?

2. I already have the brake hose kit with the 4 flexibles that replace the rubber pipes, is it possible to use the Goodridge 600 fittings into the flexibles? Obviously previously I had the end of the copper pipe to make a good seal where i now have the two metal surfaces, will I get a good seal or is there a small copper washer?

Hope this makes sence

Thanks

Stephen
