Not true of his WUR. See RarlyL8's comments.

Don't assume anything. Check it, component by component. As an example, the steel lines were first used around 1981.
Here's the bottom line. If the majority of the system is indeed from 1973, toss the whole thing and buy a system appropriate for your engine. The 1973 system didn't work all that well and changes came fast and often. There are a bunch of things in a 1973 system that won't mesh well with your car and were fixed in the later years. If you don't run a cat, I'd choose a '78/'79 US system or any ROW 911SC system.
There really isn't a bandaid fix. That's how these systems get ****ed up in the first place, by people swapping out one component or the other. Even if you fixed the mixture problem, a '73 system is way too small for your engine. Why give away horsepower, for no upside?
