I went down there to give them the correct sizes for the banjo bolts and they made them while I waited
Not at all bad for £55 I think...
High pressure line is Stainless braided PTFE hose rated at 2000 psi and the return is normal rubber hose, it did have to be stepped up for from 3/8 to 1/2 for the reservoir bottle (I really hope the E30 and E36 use the same size for this).
That price included new banjo bolts and crush washers.
I've got one of Dan's solid steering shafts, a pair of E34 steering knuckles and a couple of packs of M8 washers (spacers in kit form

) but work has interrupted my 6 day weekend

so Monday it is, gives me chance to go get some ATF though.
