I buy the annular boots from the M-B Classic Center, you have to be careful to get the boot kit without the crimp on cans .

The narrow clamps they include are tricky to install even with the correct tool .

FWIW, I bought and am still using the cheapo $10 clamp tool although a dull pair of dykes works fine .
