What's the diff between 76 & 77 hard brake lines?

[frankc]

Ok, so I know that in 77 911's got power brakes, so I assume the metal lines from the master cylinder to the front coupler & elbow going into the plastic tunnel line for the rears may be different than that of a 76, but how about the others (from the couplers to the flex lines at the corners)?

The reason I ask is that I am looking into replacing some or all of the hard lines on my car, and some of the lines seem to be hard to find - at least if ordered individually. Our host does not even seem to list the fronts for a 77 (only 78 & later), although I'm not sure what would be different between a 77 & 78.

However, I notice that Stoddard does carry a complete kit of all hard lines if you don't mind bending them yourself (which I don't). And the price is very reasonable. (makes me wonder if they are the OEM Kunifer (CU-NI) alloy style lines, or just plain steel). Anyway, (finally getting to reason for my post) they only have the kits for 911 up to 76, so if I can use everything except for the two from the MC, I'm happy. This would depend on the couplers (splitters) being in the same place both F & R, I suppose.

Any thoughts?

Oh, and does anyone know if the couplers themselves are still available? I'll need to dig out my 911 parts catalog and see if I can find some of these part numbers.

thanks,
Frank
