Ferdman,

I tried that last week. Cold called the parts dept.
" What's the VIN?"
You have in your system. Car is seviced there.
"That's not available to me."

.....later....

Ok I have the VIN now (read VIN)
" I can't give that out over the phone. You need to pull the rim and read it off the back of the rim"

Thanks for your time guy!

So, Friday I go to my tire guy and ask him for a favor to pull the rim and read it. He's busy but does me a favor. Thanks Gary!

For anyone interested the part number for 86-88 W124 rims is
1244001802.
It also has these two stampings
6.5J X 15H2 (width and diameter)
and
ET49 (no clue)

For 89 - 94 W124 rims the part number is similar, but differrent:
1244010802.
(same set of numbers, different sequence!)
