I think the title says it all! I need another fuel distribution head (I bought one but it was all rusty inside). Ideally one from the early Volvo 264/5 with the octopus/crab/spider style intake manifold, but I can make do with one from the twin-plenum arrangement if need be.

So long as it's not rusty internally and the plunger is still free, it will do the trick!
