Having a little trouble finding this part at the local auto parts store. Not really sure what the name is. It is used to connect the power booster vacuum line and the trans vacuum modulator line to the manifold. A couple of guys knew what it was, but didnt know the name and none of the stores had it.

gimme an exact application, and I can look it up in the gearhead cd, get you a GM part#

Bob, my book says it is a fitting. If you have a 69, with PB and AT, then the part number would be 3905372. The fitting is steel, with a cad plating on it. Maybe the parts store can convert it for you, but I have a source for it. Cost $15.95 each.

See page 5-5 near the lower part of the page. You will need Adobe Acrobat reader to see it.

Check Ricks First Gen. I'm not sure if its what your looking for but they have in thier catalog on page 215 intakes manifold vacuum fittings, or check their web site.

If it doesn't have to be Factory correct, try the "Help" isle at your local Checker, Auto Zone, or whatever. They come in all kinds of different configurations.
