Hub Extension Specifics 914-6, Black with 6 holes? Options

[DennisV]

Can anyone help me with specifics on the Hub extension Complete Black, part number 911-106-033-00 NLA? (aka fan housing extension, alternator shield, cooling fan hub, alternator hub, etc.)

The PDF parts catalogs seem to suggest this part number is shared with 1970-73 911 and 1978-83 turbo.

I've seen some 911 threads indicating there are 5 and 6 hole versions. Assuming the parts catalog drawing is correct, 6 is what is needed for 914-6.

Is it actually black? I've been hitting the Google machine and all I find are primer gray. Are they fiberglass with metal fins?

Thanks for your help with my tedious questions. As I dig through what we're missing, it seems like the devil is in the details. (IMG:style_emoticons/default/happy11.gif)

Here is the one with the fiberglass fins
It fits the stock Bosch alternator for the 914-6
The one on my six has the metal fins that are very similar in shape and pop rivet on like the fiberglass one.
I think this one came off a 71 911T CIS engine.
The problem with these is that the plastic cone is not very strong and many have broken mounting tabs where someone has torqued down the nuts way to much and either broken off or cracked the tabs.

Remember that this is internal to the fan housing and is not even seen from the outside.
So find a good one and use it no matter whether metal or fiberglass fins.
