Replaced 2 and 3 yesterday on the W123, took about 25-30 mins using a ~6 inch extenstion and threaded it through the fuel lines to avoid removing them. GP light still doesn't come on but it starts alot easier even just after the seat belt buzzer goes out, with some minor rumble still. Also paid $7.99 from Auto Zone.
