1.0 Parts vs 2.0

[kend]

This has probably been beat to death but I haven't found anything so here goes....I ordered a 2.0 Competitor for a customer and fell in love with it so I ordered one for me, I have a bunch of 1.0 parts and accessories left over from my SSS days but I haven't kept up with the changes. Is there a list somewhere that tells which parts will interchange between the 1.0 and the 2.0? Thanks
