Hi, Just replaced my auto dip stick tube with a new one from Mercedes. Parts Mgr asked me what my VIN # was. After I told him, he said good! Your car takes the lower cost one.
$60.00. There is another tube as you mentioned. That one is over $250.00. Parts Mgr could not tell me why it was so much more expensive. It appears that the later cars use the more expensive one. My 68 was well under the VIN # that requires the pricey one.
As a side note. The replacement tube was correct in every respect except the bracket. Not even close to the original bracket. I had to modify the mounting bracket, and use another mounting location to make it work.
I can give you the VIN #'s for the 2 tubes if needed. On another trip to the parts counter, I advised the Mgr of the problem I had. He printed out all the VIN # info, and the 2 different part #'s.
Let me know if I can help.
