The 124 diverter pod is smaller, and the older 124's have a rectangular footwell pod.
For the dual-chamber pods, the rebuild kit will fix the forward (small lift) section only. The rear (large lift) section is non-rebuildable! The kit has an interesting way to get around that, and it looks great, but DOES NOT WORK. It looks like it works, but when you apply vacuum and measure the rod travel on a new one (or good used one), compare that to the freshly rebuilt pod. The rebuild simply does not have as much travel. It all makes sense when you see it, but it's very hard to describe. That means if you use the rebuild kit, your pod won't fully open the flap it's connected to! And considering the amount of work needed to pull the dash & replace these things, you don't want to screw around. Buy NEW pods - for EVERYTHING - and replace them all at once. Believe me, it's worth it, and having the system work as intended is a beautiful thing!

Hi All - I went to order the rebuild kit for the center pod from Performance Analysis | Climate Control | Diaphragms | Blower Motors | Pushbutton Panels | Vacuum Door Locks | Autotemp | Cruise Control | Engine Oil Analysis | Mercedes-Benz Parts | Mercedes-Benz Club of America | Oak Ridge | Car Care[/url]) and they said I should order rebuild kits for all the pods, except for the oval/rectangular ones. Before sending the paypal I came accross this post so I emailed the the above text to them to get their input. Below is their response:
"That description at Peachparts.com is not accurate – my diaphragms fit and operate properly all three double diaphragm units and the single diaphragm diverter and center nozzle flap actuators. The stroke with new diaphragms from us appears shorter at first, but when they diaphragms are operated a few times the rubber stretches to provide full stroke.
Also, some customers have not re-assembled the actuator properly after re-assembly, which cause short stroke."
The response seems pretty legit to me so I think I'm going to buy as many of the rebuild kits as possibly for my 1992 300D. Has anybody ever tested the pods for an extended period of time to verify that they loosen up a bit - therefore providing the necessary amount of stroke?
