'79 CB750 Super Sport front brakes

[gph118]

New to me, 1979 750 SS complete, but the front brakes are a head scratcher. The original dual caliper set up was removed, by someone, along with the lines and junction. A single dual piston caliper on the left was installed. The master cylinder looks right but I don't think it is. I sourced a junction connector and a second dual piston right hand caliper, rebuilt both as well as the master cylinder.
I bought a three line stainless kit and this is where the scratching comes in. These lines seem to long. So, does anyone have an original set that they would measure? Also, if anyone has the correct master cylinder left over, I would be interested. The one I have will work, but looks pretty dumb and can't hold much brake fluid.
And finally, any recommendations on stainless line suppliers?

I've got a 1980 SS and it had all rubber lines. I replaced front and rear with Spiegler lines. They were perfect fit, and come in many colors. Brakes much better.

I have an 81 750 SS. That was the first year they came out with dual piston calipers. I measured the distance of the brake line from the junction to the caliper and its about 19 inches. Also attached a pic. Ya that master cylinder is pretty screwy. Hope this helps.
