Frank - you musta seen the mirrors in my accessory manual posting - I've never seen any of those in the real world, and suspect they'll be like hen's teeth, much talked of/not available! also my experience w/ mirrors on a single long arm is they vibrate so much you never have a clear view in'em any way - won't hurt to have it in the parts wanted, but don't get yer hopes up
I have seen a number of
the other style in that manual that require the extra holes, or at least I've had doors that have the mount parts still attached!
