Hi, I have a 1977 Sachs Columbia moped and needed to get a new air filter (since it is a paper air filter and should probably be replaced). I found it at www.themopedjunkyard.com but was wondering if I could get it somewhere else (like an autozone or something). Here is the url of the picture of it : http://www.themopedjunkyard.com/sachscompletecarb.jpg It is letter "D" in the picture. It would need to fit the airbox in a specific way (needs to fit the outer part labeled "B" in the pic) because the part that fits to the airbox is a rubber material that has a unique shape (shape of the outer part in labeled "b"). If anyone knows where I can get one please let me know, if you know the specific model number of the item that would help out alot. Thanks.
