Found a couple of rarer cars to find in the junkyards, a 300CD(84 IIRC) and a 87(IIRC) 300E turbo diesel. These two cars are located at the upullandpay in colorado springs.

My friend also tells me he found a w126 350SD at andersons junkyard in greely. Don't know the status of that one.

I'm not affiliated with either yard, I don't own a mercedes anymore(I've moved onto the devilish contraptions known as VW's currently). Forgive me if this isn't the correct forum to post this. I'm not selling parts nor to I want to pull them and sell them to you. I just figured I might be able to help anyone out who needs parts by giving them the heads up that the vehicles are at the yards.

Take care all.
