no sweat, we'll get it sorted.
wasn't referring to all of so cal by the way, just a smaller portion of orange county.
there are very few, if any, boutique high caliber bike shops in orange county area like above cateogry up in marin, signature cycles here on east coast, fairwheel in az, etc.
working with thm m3 cranks, if it were me, i would either do it myself (going slow, asking for lots of help or tips here on ww forum) or find someone at a reasonably local shop who's worked on them. i wouldn't be keen on paying someone to learn the in's and out's of high end product install, if you know what i mean.
but it's a moot point--it ain't my bike and it ain't my parts. i'm just helping my pal find & buy stuff on the internet.
I have a hard time thinking you or your friend can't track down a competent bike mechanic in Southern California. Barring that, rather than shipping the bike from SoCal to the East Coast, why not just send it a fraction of that way, namely to FWB in Tucson? They're getting the crank, I'd think you could trust them to install in properly.
