I owned an early production 1987 911 (Granite & Linen), with the ET
stalk. Here's what I remember.
For part of '86 and '87 the center mounted brake light was on the
bottom of the rear window.
Because it was on the bottom, when A FACTORY INSTALLED whale tail was
added, the tail's rubber lip obscured part of the light and didn't
meet the safety regs. As a result, the factory mounted tails had the
'ET" stalk. from the cabs.
In early '87 the bottom light continued --- but soon after the start
of production Porsche moved the light to the top of the window, and
didn't have the problem with the whale tail.
As a result, you'll see the ET stalk on cabs and on coupes with the
factory mounted tails (during the production of low light models).
An obscure part of Porsche history to be sure!
