Here is what I used on my 2002 base :
Cv boot clamp
Took 15 minutes to install ....fits perfectly in the groove... Oh can be re-used if you wish....
Dont overtight...... just up to the point where you cannot twist the boot anymore.
These are for the larger set. I dont remembrer the size for the smallest one.
Even if the worm is pretty small and certainly have no effect on the shaft balance .. I set them 180 deg apart.
