here is a thread with a few pics of different things. one thing I suggest was mentioned by orrieg in another thread as well. if you run the a/c or heater hoses through the inner fender or inner side cowls then it makes it cleaner looking but also makes it harder to remove the front clip later if required. a simple set up with the hoses kept independent of any aux sheet metal means the front clip can be removed without having to disconnect and purge/recharge the a/c system, the clip and engine can easily be removed and the a/c compressor can be tied up out of the way but still connected to it's system and charged with the whole time. also, in my opinion, any hoses that run through a sheet metal part are better off using bulkhead connections instead of rubber grommet protection against the sharp metal edges. that's just me though. lots of guys do the grommets.
