So the line from the master cylinder to the proportioning valve for the front brakes (closest to the firewall) is 1/2-20 at both ends?
If so, I think I can just use some 1/2-20NF to 1/8-27 NPT adapters and a couple of 1/8 NPT hoses. (Mico lock is 1/8 NPTF at both ends.) I would need to use a sealant with the NPT fittings.
