as i suggested in the post, you would need to be a magician to change its shape so that it would fit

maybe you know this, but there are two different boots; one for 55 amp alt and one for 79 amp alt. they are different shapes.

How about these boots?
Seriously, please share the VW part number that we shouldn't buy and also, is this across all VW part vendors or just one/a few?

Where did you get it? I got mine for a 55 amp on my 76 bus with the larger hole on the fan shroud from 914rubber. It wasn’t fun to install but it fit pretty well after some fiddling. It took me maybe 3 tries to get it right. I was having trouble with the snap ring on the inside staying in place. I finally smeared a nice bit of hi temp silicone on the clip and let it dry overnight. Then I fed the whole boot from inside the fan shroud.

A bigger issue you will find, is that it will likely rot in @ a year. Like a lot of new rubber these days.
Keep an eye on it, and report back. Then tell us where you got it.
YMMV

i just siliconed the old one with the clamp- there'n no way i could squish the new one around to make it fit- maybe it was the wrong one but at this point i'm trusting in the old factory model
the boot i bought has a logo like a side view of a hamburger with a v superimposed in front
022 903 655 which is 'supposed' to be for the 55A

That's so not helpful, all you have done is warned people to be extra dissapointed when they open a package after playing aftermarket parts roulette and find a certain part.
How about naming names and including what they call it on thier site?, even better with a screenshot of the page so we all know what to avoid.
Even better with some pics of the alternator and the boot going on.

the boot pictured is the 70 amp boot.
022 903 655 is the part number for the 70 amp boot.
the 55 amp boot part number is 021 903 655B. |

55A unit also uses 021 903 655D. In fact I think there might not be any (?) Buses that use "B" or possibly only Bus with 1.7l. The "B" was used on Type 4 cars and early 914. Type 4 also used "655" (no letter) and "655A" but I have no knowledge of how those two version differ from the Bus parts. (914 used "655" and "655B" but not "655A". No clue why)
The "B" part is for a fan shroud with a hole that is 36mm diameter, the "D" is for a shroud that has a 42mm hole. The "022" part number is also for 42mm shroud hole.

I believe that part of the issue is a plethora of years' worth of aftermarket boots were made using wrong molds combinations and part numbers cast in. I base this on the discovery that the originals with VW part numbers fit perfect but aftermarket ones made to look alike were impossible to use. The last NOS ones I found were perfect. There is a thread on this forum about the differences. There are also several different shrouds so boot /A may work well with alternator /B but shroud /E may need different end than boot /A. If everyone agreed to burn what is out there now, and make new molds then the problem could be solved but that will never happen. The bus is using the only NOS one I had left or I would share them.

Trying to remember....isn't there a different one for certain years of Vanagon?
Also, from what I compared a couple of years back, it appeared to me like whoever was molding some of these washers trying to make one boot that fit both part #s. Ray |

No Vanagon (aircooled) use this part, different setup with a much larger rubber boot to cool the alternator.
I don't think the manufacturer was trying to make a "one-size" boot, probably more likely a misunderstanding of which part fits which model years/engines. The "655B" 55A boot only fits Bus with 1.7l engine but often it's listed as fitting Bus '72-'79 (so 1.7, 1.8, 2.0l) It fits most (all?) Type 4 and some 914. Most Bus need 021 903 655 D since so many more Buses were made with the 1.8 and 2.0 engine.
In my experience the 022 903 655 boot for the 70A alternator fits well. It's not an easy part to install and for one thing you cannot install this without removing the fan and even then it's fiddly to install.

As far as I know the 022 903 655 boot for the 70A alternator is only being made by Airhead Parts / Ventura Warehouse Group. I am not sure how or why the OP was having difficulty installing* it but in my experience they fit fine. As I posted above this IS a fiddly part to install for a number of reasons, especially if the engine is in the Bus.
*One way I think it could be impossible to install is if you tried to install this boot on an early fan shroud with the 36mm hole. The 70A boot needs a 42mm hole in the shroud.
