This is worth at least a quick breeze through:

After it's all said and done he will have taken nearly 800 grams out of an 82mm crank, and reduced windage considerably.

I don't know if you will get this plastic one if you went to your local VW agency.  The early steel collar was used in the mid 80s by Porsche on the 924/944  The Mexican Beetles with their Brazilian made gearbox also had the steel one up to 2003.

The Ti coil strap has been in the car for about a year now.  It's quite flexy, so I had to give it a bit more slack on the 12V lead.
The stock strap is over 100g, the Ti one is under 20.
Here's the hefty Al strap (26g) that survived Central America:

I thought I found another free one with the oil filler cap.  The common stock one from the 60s and 70s is stamped from steel, and I learned the first ones used in 56 were Al, so I was on the hunt for one. 
It is a disappointment at only 10% lighter than the steel one.  This is very perplexing since Al is only 36% of the density of steel, and the sheet thickness appears to be the same.

Yep, identified by the fine serrations on the OD.  Note that it also has Al rivets!

Mystery solved.  It's steel.  I guess the magnet I tested it with was kinda weak.  It has the right colour for Al.  Maybe I will figure out how to form one myself.

Ahh, that explains it. I went rummaging around my buddy's shop for one, found a serrated one but it didn't pass the magnet test.

The pic quality goes away with re sizing for posting here, but they are machined  circumferentialy if you look.
Weights for stock 944 cv = 1490 gms.
Stock 100mm VW Bus = 1410 gms
Lightened bus cv= 1155gms.

At a local swap meet I brought along a magnet and tested oil filler caps.  The one on the right is indeed made from Al.  It's half the weight of steel.  Suspicious is the lack of the VW logo...
