Heater Core W126 85 300sd

[jfarmer64]

Need some help as I know I am close but can't seem to get there from here....

I am replacing the heater core in an 85 300sd. I have the dash out and the heater core is exposed and cannot seem to get the core free. Has anyone done this that can provide some guidance? There is a flap in the way but if I push down I can see down into the well.


The manual I have is close to this car but not quite the same. The heat control is automatic climate control and the pictures in the manual indicate manual controls. Nevertheless, the attached image (I apologize for the quality) from the manual says to remove retainer (50) and lift heat exchanger out. item 50 appears as a bar with 2 screws on the left and the right but do not see this on my auto.

Many thanks for the help!
