Another Master Cylinder Question

This ones for a '69 Falcon.

I replaced the master cylinder with a reman one this weekend and re-did my lines. I eliminated the prop valve, re-installed my line-lock to a better locale. I used -4 lines for most of it. The front port on the master cylinder has an odd size inverted flare fitting. The original steel line is usable, but slightly twisted so I'd like to replace it or better yet adapt to a -4 AN.

Anyone know what size it is? Anywhere to get an adapter fitting to a common inverted flare size or pipe thread? Should I install a different master cylinder? What would you recommend?

A good auto parts store, like a Napa or Car Quest should be able to set you up with a brass adapter. I've had to do that before also.

I would have thought that was true, but I've had no luck.

The rear reservoir adapter is 5/16 inverted flare and readily available. The front is larger, but it isn't 3/8 IF. No local shops have anything that will fit!!!

Weird.
