Looking at an '84 Vacuum Diagram, what are the "Orifice"s, as they are labeled, that connect the 3-way vacuum connectors by the transmission dashpot? Is it just like a hollow dowel? Or is it a particular sized orifice to regulate vacuum pressure?

you might want to read this thread.

Thanks Matthew, the link helped to clarify some stuff for me. I've tried finding the "Orifice" part to buy, even using the part numbers provided in that thread, and have had no luck. Does anyone know of a place online that sells them?

Thanks,
Brendan

the dealer is probably your best option, if Phil here at Fastlane can't get them.

Already tried the dealer and they didn't have them in their computer system. I'll try Fastlane though, thanks.

I think that is referring to the rubber connectors, they come in a various number of openings. MB may call them distributors.
