I bought a pair for the front end.  I was not pleased, the travel doesn't match the specifications and the quality is not comparable to the original. The protection tube is plastic.  Here are pictures of the original Fichtel & Sachs shock vs. the Cofap (Brazil) shock in the fully compressed and fully extended positions.

I guess it was too good to be true ! With the original ones north of $500 each, I will have to see if the former owner has the original ones and if so, I will have them rebuilt. If not, I will have to keep searching.

And the shocks are different for the 170S / Sb / DS / 220 ... the eBay items were for the 170V / Vb / D / Db / S-V / S-D.

Here are the original part numbers for your car

front shocks  MB#000 323 02 00    F&S# Tov 36 x 140
rear shocks   MB#000 326 02 00    F&S# Tdz 36 x 120

I'll see what is available for your car.

According to some on-line cross reference guides the new shock numbers are

front    Sachs# 106792
rear     Sachs# 113001

There are a couple of sources that make this reference, but I would check it out further.  These Sachs numbers may be what MB sells.  They are still expensive.

Sometimes the old shocks are OK, surprising given the age. Keep in mind that these shocks by design have a large difference in resistance between push and pull. Compared to other shocks they may seem like they are worn out when the really aren't.

The previous owner has disassembled them however there is a company here that can rebuild them, so I could be OK.

Good to hear that the owner had the shocks and you have a service that can rebuild them.  Mind sharing your source?

They have rebuilt a few over the years for me, including steering dampers.

I would imagine that the quantity is in the workshop manual - which I don't have as yet. As a guide, my Tatraplan uses 200cc in the front ones and 150cc in the rear.

As a point of information, the MB Service Manual and Technical Data books do not reference any shock absorber oil type or quantities of oil.  The service manual recommends that the telescopic shock absorbers be replaced; not repaired.  It would be nice to find replacements, but that is not possible in most cases.  Professional rebuilding is probably the best option.

As fat as the type of oil is concerned, the Tatraplan manual states only "Mineral oil".

The rears are very short. I doubt you would find anything similar on another car. The 300 and 300 SL are close but not the same I believe.

Thanks for tips Henry. I have filling the Fiat would be good. I need the size to match. Niemoller has them for 225 Euros but it's slightly high price.

Please forgive me if I am not on topic.  I am new to this kind of thing.  I drive a 1952 220 that I restored about 13 years ago.  For shocks, I installed Monroe #5753 on the front and #20718 on the rear and have zero issues.  Some day I am hoping to cross reference some Bilsteins, since my experience with them tells me that my car will ride much better.

I can't remember (it has been so long ago), but you may have to drive a metal sleeve out of the rubber end before they mount up.

Hello Mercrules. Thank you for your help. But here is a very strange thing - I found the front one on Monroe.com
http://www.monroe.com/en-US/catalog/e-Catalog/5753
But can't find the rear one #20718. And on the
Amazon it's looks little bit different form what we can see on Niemoller.

You can buy them both at Rock Auto. Just enter the Monroe part number into the search box and it will come up.
