V1 & V2 confusion...

I have recently purchased a used 2008 i14 T. I am doing some up grades, one of which is installing Turbo fins. My mirage drive drum is a V2 version (as per identification information given in the Mirage drive FAQ section), as is the chain. However, the sprockets appear to be the V1 version -- not threaded and have a set screw. Is this possible? A V2 drum & V2 chain with V1 sprocket? I mistakenly ordered the V2 Turbo fins and will need to return them, but first, I am double checking via this forum.

thank you for your help

V2 upgrades came over a period of time. First Drums and later the sprockets.
