I think you did what I did: mistook an early bay mirror for an early bay WESTY mirror.� The guy in the Samba thread is emphatic about the difference between the two and I, like you, wound up with a bay mirror not appreciably longer than the stock Vanagon mirror.� That is how I wound up operating on my $5 bay mirror to extend it.� If you check that thread again you'll see the bay Westy mirror stalk is significantly longer and has the nub on the backside of it, unlike the mirrors that you and�I used.

Baywindow/loaf mirror stalks, on bench and installed. Decided for
yourselves whether there is an improvement in rear visibility:
