I just recieved a 75 sporster thats been sitting for 15years. What years have the same gas tank? And what years all have interchangeable parts?

 

I believe any gas tank from 1957 to 1978 will fit. The 1979-82, 3.6 gal XLS Roadster tank will fit.

For parts best is to have a copy of the Factory Parts Catalog 99451-78B. This covers 1954 thru 1978.

You can certainly ask about specific parts and we will do the best we can.
