This thread has been dorment for over a year and the links are not found. Does anyone have the specs and dimensions and/or photos of the vacuum tubing that runs along the base of the engine block from the vacuum switch the the back of the motor? Better yet, is there a extra one --with mounting clip-- out there that's available? Have already located a new switch. My car is missing all of this, there's a pipe plug in the block, the tube is gone and the rubber vacuum line is sitting on the bellhousing. Would like to have all the pieces even if it's not functional, haven't seen inside the oil pan to know what's present or missing.
