as you may or may not know im now able to provide copper brake pipes with end fittings of choice
heres the end fitting for a set of rear lines that would be used on a stainless steel pipe upgrade

here are 2 of the rear lines made up ready to go
and for anyone concerned about the longevity of copper brake lines the lower line in this pic on its own has been in use for 7 years and still in good condition

i will try and get the lengths of the other pipes and make them available to 🙂
looking for £5 shipped for the rear pair of lines
