Needed smaller idler pulley for A/C belt travel... measured 3-1/8" and has 1/2" V-type belt used. Received correct pulley, everything is OK!

Good service, great products and quick shipping. I received a good shipping discount using Google payment. Only problem was the item was shipped to my billing address instead of my shipping address.

So I have an old car. It's and 83, seven years older than me. I'm also a student so I don't have much money and need to make as many repairs myself to save money. I go out to the local pep boys and auto zone to to try to find a repair manual that is for my old model but it's not available. I check online and there are very few copies on line. Autoplicity had the right manual at the lowest price by a good margin. <br><br>TLDR; Autoplicity has EVERYTHING and at a cheaper price

Finding what I wanted and price was all good...but after purchasing the item I was not given an estimate on the delivery date
