    chain guides (ramps)

    Hi everybody! This forum has been a fantastic source of information for the first-time porsche owner! I need to change the timing chain guides on my 72 911 t (euro). From what I have read,(Bruce Andersons performance handbook.etc.) there are 5 black(pt#911.105.222.06) and 1 brown(#911.105.222.05). When ordering the parts from the Porsche dealer, I was told that there is only 1 type,being the brown for all 6. Does the brown ones now supersede the black? can I use the brown in all 6 places? Any help here would be greatly appreciated. Thanks.

    This is taken from the Pelican Parts ( ) tech articles under the Carrera chain tensioner upgrade section:

    "There are also two different types of chain ramps use the black ones everywhere except for the slightly different brown ramp which is installed on the lower right."

    Thanks Zeke. Thats what I thought I had read so I called back the Porsche dealer today and they still maintain that all six ramps are the same Part #, that of the brown one.
