That a big joke, Sorry
But on the serious side the AX group was not made for very long and this is why the hoods are so hard to find. The set on my 3Rensho has some ill fitting hoods for this very reason. I actually could have bought a pair a few years back for about $60 usd but passed because it was just too much. Now I would gladly pay the $60 but no luck because the seller is out. its just like the story I told you about the Cinelli frame buttons where I refused to pay $40 for the darn things until they were gone and then I regretted not buying. A few month later they were available again but the price was up to $60 so I have learned my lesson.
This seller has a few hoods he sells but sadly no Shimanohttp://bicycleclassics.com
Also this site has a ton of old stuff and reproductions too just a little hard to navigatehttp://www.yellowjersey.org/index.html
I was old school before it was cool
