Greg, I just did a napa search for M2456 and they show nothing
is the number correct or maybe old?
Thank you

I think it was determined the bore was too small on that first part number...best bet is to walk in a NAPA store and let the counter person do a search for something with a 1" bore or larger. Nearly all the m/c will have a larger tank for the rear system and will be located at the back of the m/c.
