Cadillac Repair: Aux vacum pump on engine, auto recycler, autoparts store

Question
Where can I obtain a replacement vacum pump?  

Answer
Hi Ted, I would think any big autoparts store should carry them or be able to order them, the caddy dealer should unless it has been discontinued or a junk yard/ auto recycler might have a used one. You would have to call around for the best price on a new/rebuilt pump. Hope that helps. Bill
