I conducted a Google search for an obsolete service repair part and found Kauffman. Kauffman Family Tool Repair was very helpful even to the point of giving helpful suggestions on ordering the proper items

They had exactly what I needed and at a great price. Fast shipping, well packaged along with a couple of candies. Thanks! I'd be happy to buy from again.

Thanks so much K Family tools. No one in the country had the screw for a Porter Cable sawzall but you. You sent my order out and I got it in two days. Now the sawzall is a tool again!
