Fan shroud help please!

[twin plugged targa]

My 87 930 fan shroud (cooling fan surround) has cracks on the supports
I would rather find a replacement than try to repair the magnesium.

I have found a shroud (on Ebay) for a 76-79 turbo - Part number 901 106 1015R.
Mine is part number 930.106.102.4R
Is there a huge difference?
Will the older shroud fit mine?

I believe the older 76-79 has a smaller alternator and so maybe mine will not fit.
I just installed a new alternator in mine, so buying a new alternator to fit the smaller shroud is not ideal.


Anyone know of any other shrouds from other 911's which should fit??

I know when I had my 86 911 Carrera (which also had a cracked shroud) an SC shroud fitted!

Any advice appreciated
Thanks
Ben

Thanks Akila
looks like there are not any alternatives - guess I will have to try and get the shroud welded - unless I am reading that wrong?

Thanks

From the chart looks like you could use any 245 mm fan shroud from 75-89. IIRC the most concern seems to be the diameter. I was sent this chart because I wanted to find Aluminum pieces to polish. Give Ed Baus on the board a pm.

After 84 its the depth of the alternator using the large Paris Rhone.
The pre 84 used a smaller alternator (depth wise) so there is more base metal to the bottom of the alternator seat

You can always buy a repo from Vertex auto.... They are made from Al, instead of Mg... I have heard good and bad stuff about the fittment of the part.... but its new, and about the same price as a good used one, and its Al, so it can be welded on if need be

I had the same problem with my 88 turbo...
Call vertex and tell them what you have and they will send you the right one.

I looks good and fit right into the spot with no problem.

I had the same problem with my 1988 spent two weeks looking for magnesium rod to weld it and i would have had to buy 20 lbs then build a jig and machine it out. So I bought the aluminum one and it fit just about spot on with a little sanding and filing. I then primed and painted it black then painted my fan red to match my car. Looks good.
I was a little worried about the aluminum corroding with salt spray

The Vertex guys will take care of you, if you don't mind aftermarket stuff.

Vertex. Paint to your preference (mine is Zinc Chromate - an "aviation" look). Done!
