Can you in stall a 2015 and up iner and outer road glide fairing on a 2008 flhtp?

 

08 is the old frame. I would guess no, but try your dealer parts guy. Have him look up similar parts for both years, see if they match

Sorry I had the wrong yea on my question I have a 2009 Flhtp

 

It's been done but is far, far from easy or inexpensive. Also, I'm not sure I've ever read of everything (infotainment) fully working.
The way prices are right now you're way better off just upgrading to a newer bike.

 

It would probably be more sensible to try a similar year bike, rather than the later ones. The current bikes have Canbus electrics, the earlier ones like yours have the good ole fashioned kind and will be easier to get working on your bike. Look around for secondhand fairing, instruments etc, to get an idea of prices. Some dresser owners convert their bikes to RK lookalikes, so you may be in luck.
