I have a 2016 heritage. What earlier years heritage seats will fit?

will seats from any other models fit my bike?

thanks.

 

All I know is Mustang seats will not fit, 07 to 15 is different not compatible with 16. Ask me how I know, I'll tell you instead. I have a near new Mustang wide touring sitting in a box. 16 model seats did not come out to June 16 so I had to wait 7 months to get one.
