Center Support Bearing part # for 90Q?

[Nathan Belo <belo@eskimo.com>]

Can anyone verify that #26121209532 (BMW) is the right one for an '88 90Q?
I have the one from Blau for $159 and the one from TPC for $29. They look
similar, but the brackets are a little different.  The bracket on the Blau
one is flat with a small hump from the center donut.  The TPC bracket is
not flat and looks like a flattened "w" with the center being the donut
hump.  We're talking maybe half a centimeter difference between the 2.
Doesn't it matter.  We're talking $130 difference.  Center bushing and
rubber donut are the same.  The one from TPC doesn't have "BMW" on the
black donut, but the center bushings are the same (INA, 6006RS).
