66 CV Boots

[Cman]

My apology if this has been covered elsewhere.

Are 66 and 67 outer CV boots the same? I found a listing on Rock Auto for 67:

I also found these on Fusick for a 66:

They look the same, but I haven't measured. I've also heard that the single bellows boots tend to pull off the flange. Both of these are single bellows.

What source have others successfully used for inner and outer CV boots for a 66?
I can't be the first to run into this...

Please don't tell me to replace the axles. That's far too easy.

Thanks!
