It is not wise to limit one's parts knowledge to that what is found on the internet. (Good)Parts stores will have the information. It's a double-edged sword. If a parts supplier has limited information on line, he is limiting his customer base. Those that search only on line miss a lot of valuable information.
That's where counterman and machinists come into the equation. Give them a chance (maybe a parts sale or two) and they'll be happy to help you find the information you need.
I find that those who limit their parts buying to mail order houses and internet companies often get the wrong parts and information. By the time they come to me, they have wasted a lot of time and money.
