Typ 89 front brake calipers

[Radek]

Hello everyone and Happy New Year!

Since the original LF caliper in my 1988 90Q seems to be rusted beyond
repair, I ordered a brand new one.  Unfortunately, the wrong one arrived.
Could someone shed some light on what's out there as far as calipers?
The FA lists Girling and ATE.  I ordered a new Girling and received a Lucas
(apparently the same company now) but with the line connector facing down
and no thread to screw in the retaining pins.  Also, there is only one
opening for the pin to go through, while my old one has two.  Here's what it
says on the casting:  Germany, 54, CN1, 32323739/6 Lucas.
Any help will be greatly appreciated.
