Whether you are one of the fast growing "old iron" enthusiast or just a person looking for that "hard to find" part, Ebay can help you if you know how to SEARCH for what your looking for. For me, I restored an old antique John Deere Tractor and found a lot of what I needed on EBAY. The easiest way I found is to narrow your search words to Brand specific and one or two identifing words to bring up a lists of items just for the more specific items your looking for. FOR EXAMPLE:  I used the following in searching for hard to find parts I needed:  In the SEARCH field - I asked for "John Deere Unstyled" - This brought me a manageable lists of parts and items associated for Unstyled parts specifically for John Deere. If however, I had just asked for "John Deere" - I would have a list too long with things I would not have been interested in. Some other search'es I used are as follows: - I used specific model #'s or brands of items such as: "DLTX" for old unstyled carberators, "Fairbanks Morse" AND "Wico" for magnetos, "Vortox" for air breather assy's. etc. You will also be amazed at the ebay stores you will have access to from your search criteria and these can prove to be a benefit to you for finding items associated with you particular project. Hope this information helps and "Happy Ebaying"...
