Rear brake lines from caliper

[Austin09]

I’m going to change my rear calipers and discs. I’ve also got new flexible brake lines so while I’m doing that I might as well change the line from the flexi hose to the caliper.

I’ve not got a vice here so flaring my own line will be difficult so my plan was to either buy some pre bend pipes - couldn’t find any and probably a fortune - or get some pre flared line if I can work out the length with the fittings already on. There’s a company in Germany that makes the lines to length with the fittings on - anyone know the length? I might try work it out with some locking wire over the weekend.

If anyone knows where I can get pre bent ones fairly inexpensive that would save me some faff
