Do I have the correct ALDA for a 1982 300D turbo?

[Pclift]

I am a new owner of a 1982 300D turbo. I have visited this forum numerous times over the past few months. I have thoroughly enjoyed reading the posts. I find the members here to be more knowledgeble and helpful than any manuals. I also enjoy the humor and banter.

Shortly after purchasing the car, I noticed a dangling "vacuum" line. After hours of searching thru vacuum diagrams, looking at many pictures here and other places, I discovered that my dangling vacuum line is not a vacuum line but a pressure line from the switchover valve to the ALDA. Thought some of the veterans here might get a chuckle out this.

My ALDA unit differs from every unit I have viewed. Notably, my ALDA unit does not have the banjo bolt connection. It , apparently, connects directly to the unit. One manual I reviewed shows the 1982 model having the banjo bolt setup. Also, it shows the 1981 model as being directly connected. I did check my engine number (617.952) to make sure that my 300dt is a 1982 model.

My questions are:

(1) Does it really matter which connection method is used?
(2) Would I benefit from replacing the existing ALDA unit with one with the banjo bolt setup?
(3) How do I connect the ALDA line to the metal connector on the ALDA? I have a couple of thoughts. One is to use a connector like the one that connects the line to the switchover valve. Does any one know where I can find these connectors on line? The second one using white vacuum line and black vacuum hose and small clamps to mate the line with the ADLA. the black vacuum line wil fit over the metal outlet on the ALDA the white vacuum would fit inside the ALDA line.

Any and all comments are greatly appeciated. I hope sometime in the future to be able to contribute. Thank you very much
