I'd make it K-jet, if only to avoid the crumbling wiring. I've replaced fuel pressure regulator the injector hoses with (3/16" I think, softened in boiling water)nylon air-brake hose, in case you mess up one of those.

I much prefer my K-jet to my previous D-jet. I like the idea of being able to use the D-jet manifold and mechanical linkages also, but there may be more fussing than just switching the entire manifold, nuless, of course, that you've done that recently and don't want to buy another manifold gasket.

Performance I think is wholly offset by lack of susceptible electronics.
Go K-jet.
