if nothing else grab some pictures of the vac line on the other 1st gen... can come in handy, alot easier than reading a vac diagram sometimes lol...
im not sure on this, but i thought that the offy intake only went to the weber carbs, or to the holly 2 and 4 bbl... post up a pic of your intake. or a part number...
offy intakes can be found here, to know what carb fits them.
