I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again.
