House of Hose (Spokane) wil build any hose with any end for about $25. I just had (2) 20" 10MM/1.25 MA & 10MM/1.0 FE hoses made for $49 but I think you can use 4Runner hoses they are sameThat’s why I was wondering, if swapped to discs and the newer master cylinder, I’d think all ports were 10mm so making new nicopp lines or cut, re-nut and flare existing ends? On my 1970, I switched to 4Runner caliper disc brakes up front and went with 76 (or 78) cylinders in the back to go all 10mm and better brake line routing.
