Alternator, cooling boot ? Options

[luskesq]

I’m replacing the alternator in my ’70 1.7 teener. The cooling boot/vent whatever it is called was missing (99.9% of it). I located an alternator air exhaust elbow on-line that I think attaches to the port on the back of the alternator but I’m not certain where the other end goes. There doesn’t appear to be a place for it to attach to. This elbow is only about 3.5-3” overall so either it isn’t the right part or I’m missing something, figuratively and literally such as more tin. There is a small port slightly below the alt. pivot bolt area coming out of the fan housing. It has a rectangular opening of about 2” x ¾” but for all I know that is part of the heating system and the elbow I have won’t stretch that far.
Would anyone have a picture of what this “boot” is supposed to look like and how it hooks up? Comments & pics are much appreciated.

Hi Guys,

I am reviving this thread since I have some up to date info and personal experience with a source for the early Part#: 021 903 655B cooling duct from the "D" shaped alternator outlet to the larger opening cooling shroud with the internal spring clip retainer, AA Performance Products currently has them in stock.

I ordered one and installed it this weekend. Rubber seems pliable and suitably thick, fit was good. I did end up using the original worm clamp and retaining clip as they just seemed to fit a little better, but the ones with the boot from AA would work.

I found many sources but most out of stock. These guys had it in stock and I had the part in less than a week. Hopefully this helps someone.
