when looking for all the different oil filters i've used on one of those HV oil pumps and stand off filters, i found this...

its the brake line flex and solid leangths you need for a swb buggy (2075mm wheelbase), 67 with std drums all round. I gave this scrap of paper to the local brake guy and a day later, a bit of cash and a carton of beer all my lines were done...

if its helpful, use it...
